Product Description
A+E-920C pressure / differential pressure transmitter is used to measure the density, pressure and liquid level of the liquid, gas or steam, then converts them to 4~20mA DC current signal output. A+E-920C can communicate with HART manual operator to complete setting and surveillance, etc.

Static Pressure Influence:
       Measuring range code 3:  ±[0.1% measuring range+0.052% upper limit of measuring range]/3.4MPa{500psi}
       Measuring range code 4, 5, 6:   ±[0.1%measuring range+0.028%upper limit of measuring range]/6.9MPa{1000psi}
Stability (M,H and V diaphragm capsule):   ±0.2% upper limit of measuring range/60 months
Zero Adjustment:  The zero point can be PV zeroed within the upper and lower limit of measuring range. Installation position changes parallel to the membrane surface will not result in zero shift. If the installation position changes exceed 90°against membrane surface, the zero shift within 0.4kPa can be adjusted through zero adjustment.
Output: 2-wire system, 4~20mA  DC output, digital communication, it can be programmed  to set linearity or square root.
