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

A. Product Overview

This Temperature Transmitter with Display for Type 2088 Housing provides local temperature indication and a standard 4–20 mA output for industrial temperature measurement and control. It is designed to fit a Type 2088 aluminum housing and supports a wide range of RTD and thermocouple inputs, making it suitable for HVAC, building automation, clean rooms and pharmaceutical environments where both local visibility and a loop signal to the control system are required.

The transmitter uses an electrically isolated measurement design to improve signal stability and reduce interference in field installations. It features a 24-bit Σ-Δ (sigma-delta) analog front end for measurement processing and includes protection functions described as anti-surge, anti-lightning and anti-reverse to support operation in electrically disturbed environments.

B. Working Principle

The transmitter accepts an input from an RTD or thermocouple sensor, measures the temperature value, and converts it into a proportional 4–20 mA output for connection to a PLC/DCS, building management system, or monitoring loop. Sensor type selection and basic setup are performed directly from the device using the on-board keypad and display.

Configuration is performed through the on-device menu:

• TYPE: select input sensor (RTD or thermocouple)

• LOW / UP: set lower and upper range limits for the 4–20 mA mapping

• RSC: transfer adjustment used for setup trimming and applications such as Pt100 3-wire lead resistance compensation

C. Key Applications

• HVAC temperature measurement and transmission

• Building automation and BMS loops

• Clean rooms and controlled environments

• Pharmaceutical labs and pharmaceutical production areas

• Climate control in offices, utilities and industrial buildings

D. Why Industries Use This Product

A temperature transmitter with display is selected when both local indication and a standard 4–20 mA output are needed at the same measurement point. The display helps technicians verify readings during commissioning and maintenance, while the 4–20 mA signal supports integration into control and monitoring systems.

Electrical isolation improves measurement reliability in field wiring and mixed-ground installations. Protection features described as anti-surge, anti-lightning and anti-reverse support installations where electrical disturbances may impact instrumentation. On-device configuration allows quick sensor selection and range setting without requiring external tools, supporting practical commissioning 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
