Description
The CEC (H) series nuclear safety-grade capacitive differential pressure/pressure transmitter is one of the earliest domestically developed and manufactured nuclear safety-grade capacitive differential pressure/pressure transmitters in China. This product is an essential instrument for nuclear power plants and other nuclear engineering projects.
Basic Technical Specifications:
Accuracy: ±0.25%, ±0.5%
Output Signal: 4～20mA DC two-wire
Power Supply: 12～45V DC, commonly 24V DC
Ambient Temperature: H3B type and remote transmitters filled with distilled water: +4.4～+82℃; other types and remote transmitters filled with silicone oil: -25～+70℃
Ambient Humidity: 0～100%
Missing Range: Positive migration ≤ maximum measuring range
Load Characteristics: Related to power supply; the relationship between load impedance R(L) and power supply voltage V(S) is R(L)≤50(V(S)-12)
Power Supply Variation Influence: 0.005%/V
Installation Position Influence: When the transmitter diaphragm is not perpendicular to the ground, a zero-point error of no more than 0.25kPa may occur. This error can be eliminated by zeroing and has no effect on the measuring range.
