What is an explosion-proof pressure sensor?

Explosion-proof pressure sensor is a kind of sensor that requires relatively high safety performance. Its working principle is basically the same as that of ordinary pressure sensors. The pressure of the measured medium is transmitted to the explosion-proof transmitter through the connecting section. Due to the pressure of the components of the measuring head, the capacitance changes with the change of the pressure. The changing capacitance output by the measuring head is transmitted to the oscillator of the oscillation plate, and the oscillator changes the oscillation frequency according to the changing capacitance. The changed oscillation frequency signal is output by integrated operational amplification and detection to output a half-wave signal with a small oscillation frequency, and this signal is sent to Smart microprocessor. It has the characteristics of reliable working performance and high explosion-proof level. Explosion-proof pressure sensors are most used on equipment that measures gases and liquids.

 

Types of Explosion-Proof Pressure sensors

Explosion-proof pressure sensors are divided into intrinsically safe explosion-proof pressure sensors and explosion-proof explosion-proof pressure sensors according to the explosion-proof type.

 

PPM-T230E-222  Pressure Transmitter

 

The intrinsically safe explosion-proof pressure transducer is to limit the spark discharge and thermal energy of the circuit by limiting various parameters of the circuit, or adopting protection prompting, so that the spark and thermal effect generated under normal operation and specified fault conditions cannot be ignited Explosive mixtures in the surrounding environment, thus achieving electrical explosion protection. This kind of circuit itself has explosion-proof performance, that is, it is inherently safe, so it is called intrinsically safe.

PPM-T230E-230  Pressure Transmitter

The explosion-proof pressure transducer adopts an isolated explosion-proof design through the shell, and the sensor is installed in a sealed casing. The explosion-proof function is mainly brought by the shell. Of course, when the requirements are high, the intrinsic safety and explosion-proof will be done at the same time, which is called intrinsically safe explosion-proof pressure sensor. Generally, qualified sensor manufacturers can customize according to customer needs.

 

Tips for the installation of explosion-proof pressure sensor

Explosion-proof pressure sensors need to pay attention to these matters during the installation process

  1. Explosion-proof pressure transducers or transmitters must be installed in compliance with explosion-proof regulations
  2. Generally, the measured medium is not allowed to freeze, otherwise it will damage the element isolation diaphragm and cause damage to the sensor. If it is in a low temperature environment, an explosion-proof pressure sensor is required, and must be subject to low temperature resistant technical treatment.
  3. It should be installed as far as possible in a place with little temperature gradient and humidity change, no shock and no vibration
  4. Different environments need to pay attention to different problems, and the specific problems depend on the site environment
