FLP / Explosion-Proof Universal Head-Mount Temperature Transmitter

A. Product Overview

This Explosion-Proof Temperature Transmitter with LED Display is a field-mounted temperature measurement device designed for hazardous locations where an Ex-proof / explosion-proof enclosure is required. It provides local temperature indication on a high-visibility LED digital display and supports multiple configurable options for sensor type, wiring system, mechanical installation dimensions and transmitter output.

The unit is shown with an explosion-proof grade housing and a waterproof connector/shell construction. It is suitable for applications where customers need a configurable temperature assembly with choices for thread type, probe diameter, probe length, and multiple signal outputs such as 4–20 mA, 0–10 V, 0–5 V or RS-485, depending on the selected configuration.

B. Working Principle

The transmitter measures temperature from the selected sensor and displays the measured value locally on the LED display. Sensor options listed include PT100, PT1000, NTC, thermocouple and DS18B20. Based on the configured transmitter output, the measured temperature is converted into a standard signal for remote monitoring or control systems.

Output options listed include:

• 4–20 mA

• 0–10 V

• 0–5 V

• RS-485

Mechanical ordering/configuration options include thread specification, probe diameter, cold end length (LC), hot end length (LH) and selectable temperature ranges. Wiring system options are listed as 2-wire, 3-wire and 4-wire, enabling matching to the selected sensor type and installation requirement.

C.Key Applications

• Temperature measurement in hazardous areas requiring an explosion-proof enclosure

• Field temperature monitoring where a local LED display is required for quick verification

• Skids and process equipment requiring customizable sensor type, wiring and mechanical dimensions

• Installations needing selectable output signals such as 4–20 mA, voltage output or RS-485

D. Suitable Buyers

• OEMs building skid packages and hazardous-area equipment requiring explosion-proof temperature measurement with local indication

• EPC contractors specifying Ex-proof field instruments with configurable outputs and mechanical options

• Maintenance and utilities teams replacing explosion-proof temperature instruments where field display is required

• Plant engineering and procurement teams standardizing installation formats (threads, lengths, diameters) for retrofit and expansion projects
