Universal Head-Mount Temperature Transmitter with Display (Loop Powered)

A. Product Overview
This Temperature Transmitter with Display is designed to fit a Type 2088 aluminum housing and provide local indication plus 4–20 mA transmission for industrial temperature measurement. It supports thermocouple and resistance (RTD) signal transducers and uses an electrically isolated design for measurement reliability. The transmitter includes a 24-bit Σ-Δ analog front end and protection features described as anti-surge, anti-lightning and anti-reverse. The device is intended for temperature measurement points where a local display is useful while still sending a standard 4–20 mA signal to monitoring or control systems.

B. Working Principle
The transmitter accepts a temperature sensor input (RTD or thermocouple) and converts the measured value into a 4–20 mA output. Sensor type is selected through the on-device menu. The setup interface uses the SET key and arrow keys to enter settings, select parameters, and save values. Available menu items include sensor TYPE selection, LOW and UP limits, and RSC transfer adjustment. A lead-resistance compensation example is provided for Pt100 3-wire wiring using the RSC setting. Electrical isolation is specified for the product.

C. Key Applications (Bulleted)

• Heating, ventilation and air conditioning (HVAC)

• Building automation

• Pharmaceutical labs and pharmaceutical industry

• Clean rooms

• Climate control in office buildings

D. Why Industries Use This Product
Industries use a transmitter with display when they need both local visibility and a standard 4–20 mA signal for integration. Local indication helps technicians verify readings at the field point while the 4–20 mA output supports connection to control or monitoring loops. Electrical isolation is specified to improve measurement robustness. Protection features described as anti-surge, anti-lightning and anti-reverse are included for installation environments where electrical disturbances can affect instrumentation. The on-device configuration for sensor type and limit settings supports practical commissioning and adjustment at site.

E. Suitable Buyers

• OEMs integrating RTD/thermocouple measurement points with local indication in equipment using Type 2088 aluminum housing

• EPC contractors standardizing 4–20 mA temperature loops with field display for commissioning and handover

• Maintenance and utilities teams commonly using it for replacement where 4–20 mA output and local display are required

• Plant engineering and procurement teams preferring standardized installations and retrofit projects using Type 2088 housing format

FAQ SECTION

What sensors does this temperature transmitter with display support?
It supports thermocouple and resistance (RTD) signal transducers. The TYPE menu lists sensor selections including K, E, S, B, J, T, R, N, Pt100, Cu100 and Cu50.

What output signal does the device provide?
The specified output is 4–20 mA.

What power supply is required and what load can it drive?
Working power supply is 12–35 VDC. The specified load is 500 Ω or less.

How is the transmitter configured on the device?
Configuration is done using the SET key and arrow keys. Long press SET to enter setting mode, use ▲/▼ to select items, and short press SET to enter and save. Menu items include TYPE, LOW, UP and RSC.

What is RSC and when is it used?
RSC is listed as transfer adjustment. The document provides an example of using RSC for Pt100 3-wire lead resistance compensation.
