Two-wire 4~20mADC and overlay digital signal in line with the
HART protocol.

Loop Rmax maximum load resistance depends on the power supply
voltage. HART communication require the load resistance no less than 250Ω, and no
more than 600Ω

The maximum communication distance is 1.5Km,
Multistation communication can take up max15 units smart pressure transmitter.

Zero point can be arbitrary positive transfer and negative transfer,
but the upper and lower limit of measurement range and pressure range should not be
set exceeded.

Environmental temperature: -40~85℃
(-20~70℃ when select LCD indicator)

Medium temperature:-40~104℃

Static and
Unidirectional
Pressure Range

3.45Kpa(absolute pressure); 31.2MPa(gauge pressure)

If there is a breakdown of sensor or circuit, automatic diagnosis
function will automatically output 3.9 or 21.0 mA

In order to avoid the transmitter is randomly change the
configuration data, can lock the stored data by software or protection switch.
