Sitron's Line Of Conductive Level Switches

Product catalog summary
Introduction
Sitron's Conductive Level Switches are designed for controlling the level of conductive mediums with up to five detection points. They feature fixed, removable rods, or pendular electrodes, suitable for alarm point detection and on/off pump valve control. These switches are known for their easy installation and maintenance-free reliability.
Technology
The switches operate by detecting electrical resistance variations between electrodes. A conductive tank wall can serve as a reference electrode, or an additional electrode is needed for non-conductive tanks.
Models
- CLF: Fixed rods, up to five detection points.
- CLR: Removable rods, up to five detection points.
- CLP: Pendular electrodes, ideal for deep wells or tanks.
- CLE: Single pendular electrode without enclosure.
- CL1-DC: Single point detection with built-in controller.
- CL2-DC: High and low point detection with built-in controller.
Features
- Easy installation and operation.
- Rugged construction and low cost.
- Built-in units with up to five points of level control.
- Available with 316 S.S. sanitary, flange, or threaded connections.
Controllers
- BS/16: Controls high and low levels with sensitivity adjustment, 1 SPDT contact.
- CN/16D: Controls two independent levels, 2 SPDT contacts, sensitivity adjustment.
Both models can be used in combination for multiple control functions and are available with DIN rail sockets or screws.
Specifications
- Operating temperature: 14 to 248º F (-10 to 120ºC).
- Max pressure: 290 PSI (20 Bar).
- Enclosure material: Glass filled nylon.
- Process connection: 1/2” to 1 ½” BSP or NPT sanitary and flanges.
Applications
Suitable for level detection of conductive liquids in tanks and pipes, with various configurations for different application needs.
Additional Specifications
The document outlines specifications for conductive level probes used for point level detection. These probes can be customized by cutting rods to suit specific applications. The rods must be coated when used in temperatures above 180°F (80°C).
Ordering Information
The document provides ordering information for conductive level probes with removable rods, which are compatible with BS/16 or CN/16D controllers. Various process connections are available, including 1/2", 3/4", 1", and 1 1/2" threads, as well as a 1 1/2" Tri-Clamp. Customers can specify the number of rods or electrodes needed for level detection, with options for 5 rods or electrodes for 5 points of detection.
Built-in Units
Conductive level probes with built-in electronics are available with 1 or 2 fixed rods. These units integrate electronics into the enclosure and offer various process connections, including NPT and Tri-Clamp. The enclosure is made of glass-filled nylon, and the rod's length can be specified.
Electrical Connection
Options for electrical connections include a cable gland with a 1/2" NPT conduit entry and an M12 connector. Coating options include Hallar - Tefzel and Epoxy.
Notes
- All conductive applications must have a reference point, such as a metallic tank wall, or an additional rod or electrode if the tank is non-metallic.
- Rods can be custom cut by the customer to better suit the application.

Sitron's Line Of Conductive Level Switches-1

Models: > CLF-(1 up to 5) Fixed Rods CLR-(1 up to 5) Removable Rods CLP-(1 up to 5) Pendular Electrodes CLE-1 Pendular Electrode without enclosure CL1-DC Single Point Detection/Controller built into the housing CL2-DC Low & High Level Point Level Detection/Controller built into the enclosure Controllers: > BS/16 CN/16D Introduction > Sitrons line of Conductive Level Switches offer a wide range of customized options to meet any application's need. CL models are designed to control the level of all conductive mediums with up to 5 different points of level detection. Models are available with Fixed rigid rods, Removable rigid rods, or with Pendular electrodes attached to the housing with cables. Applications involve both alarm point level detection as well as on/off pump valve control. Like all of Sitron's products, the series of Conductive Level Switches feature easy installation and maintenance free reliability. Technology > The probes work through the variation of the electrical resistance between the reference electrode and the level control electrode. Conductive Level Switches detect the level resistance when their electrodes are covered by the medium. An electrically conductive tank wall may be used as the reference electrode. If the tank is made of plastic, concrete or any other non-conductive material, an additional electrode is required to act as a reference. size="-2">

Sitron's Line Of Conductive Level Switches-2

The CLE CLP-(1 up to 5) CLR-(1 up to 5) CLF-(1 up to 5) is a single pendular electrode without the enclosure or the process connection. These models are all used along with an external controller. However, there are two other types of conductive probes that do not require an external controller. The has has removable rods designed for easy handling and installation and is also available with up to five points of level detection and control. The has fixed rods and is available with up to five points of level detection and control. The pendular electrodes designed for deep well or tank applications...

Sitron's Line Of Conductive Level Switches-3

Sitron's model CLF (1 up to 5) level switch is the most commonly specified conductive level switch.The CLF (1 up to 5) can accommodate up to five 316S.S. fixed rods for five (or more upon request) different levels of control. The rods are isolated with a PTFE joggle and can also be coated with PTFE or epoxy when the probe is applied in aggressive or sticky mediums prone to build up. Operating levels in the tank can be easily modified by cutting the length of the electrodes. Like all of Sitrons products the CLF models have a rugged, compact and modern no-moving-parts design. This makes the CLF...

Sitron's Line Of Conductive Level Switches-4

Along with the same features as the CLF model, the CLP (1 up to 5) comes with unique removable 316S.S. threaded rods, which make it possible to switch the rods. Rods can be ordered separately in longer length and can then be custom cut to fit any type of application. Removable rods make the system more versatile, easier to handle as well as more forgiving if the rod's length is cut incorrectly. CLR model probes are available with 316S.S. threaded, flanged or with sanitary connections.CLR models are also used along with two types of controllers: The BS/16 and the CN/16D.We do not recommend any...

Sitron's Line Of Conductive Level Switches-5

Along with the same features as the rigid rod probes, Sitron's CLP (1 up to 5) pendular probes can also accommodate up to five CLE electrodes (or more upon request). The CLP probes are ideal for deep measurements in wells or large tanks where long rods would be impractical, but they work equally well for shorter length applications. Because the electrodes are hung from PVC cables that allow for longer lengths, installation and handling are made easy. As with all of Sitron's other products, these probes are highly reliable as well as low in cost. CLP model probes are available with 316S.S. threaded,...

Sitron's Line Of Conductive Level Switches-6

These conductive liquid level controllers are used to power all of Sitron's level probes. The BS/16 and the CN/16D are electronically controlled devices that open and close an electrical contact to effect the operation of other devices in the same, or another, electric circuit. The CN/16D BS/16 BS/16 and the is able to control the differential of high and low level with an adjustment for sensitivity. The controller has 1 SPDT contact. The controls two independent levels and has two SPDT contacts. It also includes a sensitivity adjustment. The CN/16D are designed so that multiple units may be...

Sitron's Line Of Conductive Level Switches-7

The CL1-DC operate with identical features offered with Sitron's other conductive models, with one added feature: The entire electronic controller is contained within the enclosure. The CL1-DC has one single rod and is able to control one point of level. The model CL2-DC can accommodate up to two rods and is able to control high and low level. Both models feature a 24VDC power supply and internal controller that replaces the need for an external controller. As with all other conductive probes, the rods for these two models can be custom cut and made with any process connection, such as threaded,...
