Description:
Ultra low temperature pressure sensors using  stainless steel integrated package, excellent sense of laminated film using special design, security and stability of the sensor to work at extremely low temperatures -196 ℃ environment, small size, high accuracy, high frequency dynamic response , corrosion resistance, long working life. Our professional technical team to provide you with customized services.
 
Main applications:
  Low scientific experiments, liquid oxygen, liquid nitrogen, liquid hydrogen, liquid helium
  Pressure cooling tanks, cryogenic tanks, cryogenic propellants measure
  Aerospace, aviation, ships and other low-temperature storage tanks, etc.
 
Parameter:

 
 
 
 
 
Type 1
Special treatment, micro structure, mV output level, the whole can work under -196 ℃ environment. Stable performance, long life. With external transmitter output 4-20mA current or voltage signal 0-5VDC.

Type2
Special treatment, mV output level, stable work environment at -196 ℃; high precision, long life, a variety of optional mounting screw; special type highest -250 ℃, with an external transmitter output 4-20mA current or 0 -5VDC voltage signal.

Type3 
Integrated structure, built-in amplifier; measuring medium temperature: -196 ℃ ~ 150 ℃, the working environment temperature: -40 ~ 105 ℃; 2-wire 4-20mA current loop or 0-5VDC output.


Type4 Cryogenic vacuum sensor, differential pressure sensor
Special techniques to measure ultra-low vacuum, measurable -196 ℃, vacuum degree of -255 ℃. Optional threaded mounting, quick release flange, straight tube is inserted in several ways; 0.018Pa ~ 200Pa, 1Pa ~ 1kPa, 10Pa ~ 10kPa, 100Pa ~ 100kPa, 1kPa ~ 1Pa vacuum pressure, 0- ~ 100kPa negative pressure fit range .differential type


Type5   Ultra-low temperature pressure sensors (industrial shell type)
Industrial shell structure, low temperature sensor probe, conversion circuit placed in protective casing, with good protection, measuring medium temperature: -196 ℃ ~ 150 ℃, -250 ℃ ~ 55 ℃, the working environment temperature: -40 ~ 105 ℃; 2-wire 4-20mA current loop or 0-5VDC output.

 
Type6 Ultra-low temperature pressure sensor (high frequency response)
Quartz resonant principle, compact structure, easy installation, the ability to measure fluid pressure -196 ℃, is characterized by fast response frequency, the natural frequency of about 100kHz, at low temperatures, ideal for environments requiring high-speed measuring pressure changes.
