HTM128 explosion-proof temperature transmitter is specifically designed for use in hazardous environments where there is a risk of explosion. It supports the use of PT100, PT1000, or thermocouple sensors as the signal measurement components, offering flexibility to accommodate different temperature sensing requirements.


The transmitter features an amplification circuit housed within a robust stainless-steel shell. This circuit converts the sensor signal from the PT100, PT1000, or thermocouple into a standard signal, such as a current or voltage output. The stainless-steel shell ensures protection and integrity of the electronics in hazardous environments.


With its excellent reliability, the HTM128 transmitter is widely used for on-site temperature measurement and control in various industrial processes. It finds applications in industries such as petroleum, chemical, metallurgy, electric power, hydrology, and more, where explosive atmospheres may be present. Its adaptability, flexibility, and diversity make it a trusted solution for temperature monitoring and control in hazardous industrial settings.
