THLL331 Explosion proof Pressure Sensor

product description

The THLL331 explosion-proof pressure sensor uses a diffused silicon pressure core as the sensitive component, and a built-in processing circuit converts the sensor's millivolt signal into standard voltage and current signals for output. It can be directly connected to computers, control instruments, display instruments, etc. Capable of long-distance signal output. Adopting an integrated all stainless steel structure, it has undergone multiple stainless steel welding processes to meet explosion-proof design requirements and can be used for a long time in harsh environments. The product is easy to install and has extremely high resistance to vibration and impact. It is widely used in flammable and explosive environments in industries such as petroleum, chemical, power, hydrology, geology, and shipbuilding.
