EB RF-Capacitance Level Transmitter

Product catalog summary
Product Introduction
The RF-Capacitance Level Transmitter models EB3999 and EB2600 measure liquid levels using capacitance between the sensing probe and the reference probe or metal vessel wall. Capacitance increases with the medium level, enabling precise detection.

Principle
The transmitter's operation is based on the principle that capacitance is proportional to the medium level, with the medium's dielectric constant being higher than air, thus increasing capacitance as the level rises.

Features
The EB Series features a 4~20mA two-wire loop power system, low power consumption, high accuracy, temperature compensation, and easy calibration. It has a wide measuring range of 0~5000pF and is suitable for various tank sizes and environments, including high temperature, high pressure, and corrosive conditions.

Specifications
- Output Current: 4~20mA
- Operation Voltage: 12~36Vdc
- Accuracy: <1% FS
- Operating Temperature: -40~200°C depending on the model
- Housing IP Degree: IP65

Standard Types
Models include wire probes, rod probes, and anti-corrosion types with coatings like PVDF, PP, and FEP, designed for specific applications such as non-conductive or corrosive materials and different tank sizes.

Calibration & Setup
The system supports easy calibration with settings for display value, alarm modes, and control modes, including memory storage and software filtering.

Order Information
Models are categorized by probe type, material, and coating options, with customizable product length and specifications.

Explosion Proof Type
Models EB1710 and EB1720 are designed for explosion-proof applications, suitable for non-conductive materials and various tank sizes, with safety certifications.

Specifications
The document details various probe types and specifications, including wire and rod probes, high-temperature variants, and anti-corrosion options, noting that characteristics and dimensions may change without notice.

Installation Procedures
1. Install probes parallel and close to the tank wall, avoiding medium sticking between the probe and wall.
2. Use a metal strap or tube for non-conductive tanks.
3. Use a metal tube with a vent hole for irregular-shaped containers.
4. Fix cable probes with a ceramic isolator for non-conductive mediums.
5. Use non-conductive materials to fix probes to prevent deformation or tangling.
6. Coat probes with PVDF or PP for conductive mediums.
7. Ensure proper grounding for device operation.
8. Seal and tighten housing covers to prevent moisture ingress.

Product Range
The document lists various level switches and transmitters, including paddle flow switches, float level switches, capacitance level switches, and radar level transmitters.

EB RF-Capacitance Level Transmitter-2

PRODUCT INTRODUCTION RF-Capacitance level Transmitter utilizes the capacitance formed between the sensing probe and the reference probe or the metal vessel wall to calculate the level of the liquid/medium inside the vessel according to the capacitance theory that the capacitance and vessel are proportional increased. When sensing probe and detected media are fixed, media dielectric constant (Kmedia) is normally bigger than air (Kair=1). Capacitnce for media (Cmedia) increases when liquid/ power/ solid level raise. EB prouduct detects media level by calculating capacitance inside the tank. • 4~20mA...
