CONDUCTIVITY LEVEL CONTROLS

Product catalog summary

Technical Characteristics
The document details the technical specifications for conductivity level controls, specifically models CL1001 and CL1002. These models support supply voltages of 24-110-220V ± 15% at 50-60Hz, with a voltage between electrodes of 12Vac and an absorption of 3.5VA. Relay outputs are rated at 5A at 220Vac. They operate within a temperature range of -20 to +60°C and have an IP40 protection rating. Sensitivity is adjustable from 2 to 40 KOhm, with higher sensitivity options available upon request.

Ordering and Sensitivity Ranges
The document provides guidance for ordering based on sensitivity ranges: low sensitivity (200 ohm to 10 KOhm), standard sensitivity (2 KOhm to 40 KOhm), and high sensitivity (10 KOhm to 200 KOhm). For sensitivities beyond 200 KOhm, consultation with the manufacturer is recommended.

Available Models
Three models are available: CL1001/O, CL1001/U, and CL1002/U. CL1001/O is a single voltage level control with an octal base, CL1001/U is a multi-voltage level control with an undecal base, and CL1002/U is a single voltage level control with a relay output featuring a 2 pole changeover.

Working Principle
The level controls operate based on the conductivity of liquids, using electrodes to detect the liquid level. The presence of liquid between the electrode and the container's metal surface triggers the electronic circuit, causing the relay to switch. The devices can also detect solids if the material's conductivity is within the unit's range.

Level Control Procedures
Instructions are provided for one-level and two-level control systems, both for filling and emptying operations. The document specifies the use of reference probes and the appropriate relay contacts for each operation.

Additional Features
The document mentions an optional anti-wave delay feature to prevent unwanted relay switching due to liquid turbulence. It also describes the use of electrode holders for conductivity level controls, with details on the construction and materials used for the electrode holders.

Level Control with Four Distinct Levels (CL2004)
This section describes a device that manages four independent relay outputs based on input from a level transducer. The device allows for setting four distinct levels using frontal trimmers and includes indicators for output activation and power presence.

Electrode Holder for Conductivity Level Controls
The document describes electrode holders suitable for use with CL1001 and CL1002 level controls. These holders are made from stainless steel or plastic and are designed to prevent water ingress and oxidation.

Overview
This document provides technical specifications and applications for various types of level control detectors and electrodes used in industrial settings such as boilers and autoclaves. The detectors are designed to operate under specific pressure and temperature conditions and are made from materials like stainless steel and thermosetting plastic.

One Pole Detector Type CL-A
This detector is suitable for high-pressure and high-temperature environments, such as boilers and autoclaves. It features a stainless steel holder with a rubber protective cap, teflon insulation, and a stainless steel electrode support. It can withstand pressures up to 12 kg/cm² and temperatures up to 200°C.

Two Pole Detector Type CLK-A
Designed for use in metallic tanks, this detector simplifies electrical connections by eliminating the need for a separate earthing probe. It includes a stainless steel holder with a three-pole connector, teflon insulation, and can operate under a maximum pressure of 12 kg/cm² and a temperature of 100°C.

Three Pole Detector Type CL3-A
This detector is made from thermosetting plastic and is suitable for non-pressure applications with temperatures up to 70°C. It includes a terminal block cover and brass holders for electrodes, which are not included. A metallic bracket for fixing is available upon request.

Electrodes
Electrodes are available in five lengths (100, 300, 500, 700, 1000 mm) and are made from stainless steel AISI 316 with a diameter of 4 mm. They can be used with CL-A, CLK-A, and CL3-A detectors using special adapters. When ordering, specify the length with the prefix 'E' (e.g., E-100).

General Characteristics
The detectors are designed for sensing conductive liquids and are compatible with level controls CL1001 and CL1002. They consist of a stainless steel or plastic electrode holder and a separate electrode, which can be customized in length according to requirements.

CONTROLLI DI LIVELLO A CONDUCIBILITÀ SERIE CL1001-CL1002 CONDUCTIVITY LEVEL CONTROLS CL1001-CL1002 SERIES WORKING PRINCIPLE I controlli di livello CL1001-CL1002 funzionano sulla conducibilità dei liquidi e rilevano il livello tramite degli elettrodi posti nel liquido stesso. La presenza di liquido tra l’elettrodo (o gli elettrodi) e la superficie metallica del serbatoio (o elettrodo di massa) provoca il funzionamento del circuito elettronico posto nell’unità di controllo e la conseguente commutazione del relè di uscita. Si può effettuare anche il rilevamento di solidi purchè la conducibilità...
