Model HT82 Methane Gas Detector
The Model HT82 methane gas transmitter features an explosion-proof enclosure and is designed for methane leak detection. With a measurement range of 0–100% LEL, this detector offers broad sensitivity to various combustible gases, including butane, propane, ethane, hexane, pentane, hydrogen, and carbon monoxide. The Model HT82 is equipped with a 4–20 mA current output, a 0–10 V voltage output, two relay outputs, and a MODBUS/RTU-RS485 serial port. This device is suitable for measuring methane and detecting combustible gases in potentially explosive environments. The price of the detector varies based on its features; furthermore, custom versions—including those designed for different gas concentration ranges—can be manufactured to meet specific customer requirements.

Applications of the Methane Gas Detector and Transmitter
The use of methane gas sensors and detectors is of great importance in environments where the accumulation or leakage of this gas is possible. Applications for methane gas detection equipment include the following:
Oil, gas, and petrochemical industries
Refineries and gas processing units
Boiler rooms and industrial facilities
Power plants and energy generation units
Natural gas storage tanks and related infrastructure
Factories and industrial environments where flammable gases are present
Gas monitoring and control systems
Distinctions Between Methane Sensors, Detectors, and Transmitters
While the terms "methane gas sensor," "methane gas detector," and "methane gas transmitter" are sometimes used interchangeably, there are technical differences between them.
A methane gas sensor is the sensing component of a device responsible for detecting the gas. A methane gas detector refers to a piece of equipment used to identify the presence of this gas. A methane gas transmitter, in addition to measuring the gas, transmits data regarding its concentration—in the form of an output signal—to monitoring systems, controllers, or peripheral equipment.
Purchasing Methane Gas Transmitters and Detectors
When purchasing an industrial methane gas detector, one should consider factors such as the measurement range, measurement accuracy, sensor type, response time, output type, installation conditions, and compatibility with control systems.
