Can pressure transmitters measure high temperature media?

Customers often have such a question. So can pressure transmitters really measure high temperature media? The answer is yes.Of course, the pressure transmitter cannot directly contact the high-temperature medium. Prolonged contact with high-temperature media can easily damage the pressure sensor. Usually when measuring high temperature media, the pressure transmitter will be equipped with a stainless steel heat sink device. Avoid direct contact between the medium and the transmitter. A condensing tube can also be added on the basis of the heat sink to reduce the damage to the transmitter caused by excessive temperature.

High temperature-resistant pressure transmitters use Hessman connectors to keep the signal stable, the circuit design is constantly optimized, and the anti-interference ability is strong. The heat sink and core are fully combined to work normally at high temperatures.

High temperature-resistant pressure transmitter:

  1. Adding stainless steel heat sink on the basis of standard type and industrial type is high temperature type product, divided into standard high temperature type and industrial high temperature type. 4 ~ 20mA output, voltage 0 ~ 5V / 1 ~ 5/0 ~ 10V, etc.
  2. Standard high temperature type, all stainless steel structure, small size and easy installation. High temperature industrial type, cast aluminum housing, terminal output and simple wiring. When the current output is required, a digital display meter can be optionally provided.
  3. Standard high temperature type, high temperature industrial type, optional intrinsically safe explosion-proof box isolation and explosion-proof.
  4. The computer compensation technology is adopted, and the temperature drift is small. ± 0.01% FS / ℃ integrated circuit, high precision, strong anti-interference ability.
  5. Applied in petroleum, chemical, steel, light industry, machinery and equipment, energy constant pressure variable frequency water supply and other industries pressure detection. When the temperature is quite high, a condenser tube or a condenser is still used.

Add-on High Temperature Adapter

Add-on High-Temperature Adapter can also be called a pressure buffer tube. The role is to cool the measured medium and smooth the pressure fluctuations. When the pressure of the liquid, steam, and condensable gas whose temperature is higher than 60 ℃ is detected, the source port of the pressure sensor installed locally shall have a ring-shaped condensation ring or a U-shaped condensation bend.

Add-on High-Temperature Adapter is mainly used in a high-temperature environments with permeable or saturated steam. Avoid direct contact with high-temperature fluid inside the pressure sensor.
