Product details
Technical performance
Target audience: liquids, gases, or vapors
Measurement range: refer to the selection specification table
Output signal: 4-20mA DC output, combined with HART protocol digital signal (two-wire system)
Power supply: External power supply 24V DC, Power supply range 12V~45V
Load characteristics:
Installation in hazardous areas: Explosion proof dIICT5;
Intrinsic safety type iaIICT5;
Migration characteristics:
At the minimum range (compression ratio of 40:1), the maximum positive transfer zero point is 39/40 times the upper limit of the range, and the maximum negative transfer zero point can be the lower limit of the range,
Absolute pressure transmitter has no negative transfer. Regardless of the output form, after positive and negative migration, the upper and lower limits of the range must not exceed the limit of the range
Temperature range:
The electronic circuit board operates at -40~85 ℃;
Sensitive components operate at -40~104 ℃;
