Functions of single-flange pressure transmitter
Output: 2-wire, 4～20mA DC output, digital communication, programmable set linear or square root output mode, HART protocol loaded on 4～20mA DC signal.
Power supply voltage: working condition: 10.5～42V DC
Digital communication: 16.4～42V DC
Intrinsically safe: 16.4～30V DC
Load (when output signal code is D and E): Operating status: 0 to 1335Ω Digital communication: 250 to 600Ω
HART Communication Distance: The communication distance can be up to 2Km with multi-core twisted pair cable, and the communication distance varies depending on the cable type. The formula is as follows: L=65000000/(R×C)-(C1+10000)/C
L=Length (m and ft)
R=impedance (Ω , including power supply impedance)
C = cable capacitance (pF/m or pF/ft)
C1=maximum parallel capacitance (pF/m or pF/ft)
Damping time constant of monoflange pressure transmitter: the sum of damping time constant of amplifier parts and membrane box. The constant is adjustable in the range of 0.2 to 64 seconds.
Ambient temperature: -40～85℃ (-40～185?F) -30～80℃ (-22～176?F) [with LCD meter head].
