EF By-Pass Level Transmitter

Product catalog summary

Introduction
The Fine-Tek By-Pass Level Indicator is designed for external installation on tanks or vessels, allowing for easy observation of liquid levels through color-changing flags. It operates on the hydrostatic principle with a magnet-equipped float, suitable for high-temperature, high-pressure, and corrosive environments, and is unaffected by power failures.

Applications and Features
This device is applicable in industries such as textile dyeing, sewage processing, power generation, and petrochemicals. It offers optional magnetic switches and level transducers for electrical signal output and level transmission. The magnetic switch is compact, anti-corrosive, and IP67 rated, allowing real-time adjustments.

Specifications
The By-Pass Level Indicator is available in various models with specifications including:

Operation Temperature: -20 to 400°C depending on the material.
Materials: SUS304, SUS316, PP, and PVDF.
Operation Pressure: Up to 50 kg/cm².
C-C Distance: 150mm to 5800mm.

Installation and Design
The design includes a removable duct and connecting flange for easy installation and maintenance. The bottom end flange design ensures no residue remains in the chamber, suitable for processes requiring frequent liquid changes.

Magnetic Switch and Level Transducer
Magnetic switches are available in economy, standard, and explosion-proof models, with contact ratings of 1A/30W/200Vdc/240Vac. Level transducers provide 4-20mA output for level monitoring and control, with explosion-proof options.

Flag Display and Ruler
Flag displays are made from engineering plastics or ceramics, with operation temperatures from -20 to 400°C. Rulers are available in SUS304 or plastic, with custom scales.

Conclusion
The By-Pass Level Indicator by Fine-Tek is a versatile and reliable solution for liquid level monitoring in various industrial applications, offering durability, ease of installation, and optional upgrades for enhanced functionality.

Overview
This document provides technical specifications and ordering information for intrinsically safe explosion-proof transmitters and related components used in industrial automation for monitoring and controlling liquid levels.

Specifications

Models include EG37 and EG31 series with outputs such as Modbus RS-485 and 4~20mA in both standard and reverse directions.
Non-linearity: K0.05% F.S or 1.0mm, whichever is greater.
Operating temperature: -30°C to 200°C.
Output: 4~20mA with RS-485 communication and loop power of +24Vdc ±10%.
Protection rating: IP67.

Procedures

Installation requires a 250mm space and no external magnetic interference within 10cm of the magnetic switch.
Magnetic switches should be positioned correctly and protected from extreme shocks.
Wiring must be completed before actuation, and high-temperature materials should not contact the unit's cables.

Standards and Recommendations

EG transmitters are not suitable for Blanket type, Jacket type, and Removable Insulation type installations.
Special terms for LR Marine approval specify environmental tests but restrict certain pipe fittings.

Ordering Information

Order codes and configurations are provided for various models and accessories, including magnetic switches, level transducers, and connection types.
Materials and pressure ranges are specified for different components, with customization options based on application needs.

Key Components

Magnetic Switches: Available in economy, standard, explosion-proof, and adjustable types.
Level Transducers: Options include 2-wire and 3-wire configurations, with explosion-proof variants.
Rulers: Available in stainless steel and plastic, both metric and imperial.
