Product Description
Brief Introduction
Gauge Pressure Transmitter (GP)
Absolute Pressure Transmitter (AP)
Measured media: gas, steam, liquid
Measured range(with no shift): 0Pa~600Pa…40MPa
Basic error: ±0.075%
Diaphragm contacting with liquid: Stainless Steel 316L,
Hast-alloy
Pressure transmitter includes two functional units:
Main unit
Auxiliary unit
Main unit includes sensor and process connection, working principle as followed:
Through corrugated, isolated diaphragm and filling oil, process media is pressurized to diaphragm of
pressure sensor. The other end of pressure sensor diaphragm is connected to the air (for gauge
measurement) or vacuum(for absolute measurement). In such way, it makes the resistor of sensor die
change so that the detection system outputs different voltage. The output voltage is in proportion to the
pressure variation, and then it is transmitted to standard output by adapter and amplifier.PT40MS-GP Pressure Transmitter
PT40MS-AP Absolute Pressure Transmitter
PT40MS series gauge/absolute pressure transmitter is used for level, density, pressure and flow
measurement of liquid, gas and steam. Then it will outputs 4mA~20mA DC HART signal and also it could
be connected to RST375 handing communicator or RSM100Modem to do the specification setting and
process control.
Standard Specification
(Standard zero as the reference calibration range, Stainless steel 316L diaphragm, filling liquid is
silicone oil)
1 Performance Specification
Reference Basic error for range calibration (including linearity, hystersis and repeatability from zero):±
0.075%
If TD>10 (TD=Max. Pressure range/calibration range), the Basic error is ±(0.0075×TD)%
The Basic error of square root output is 1.5 times of above reference Basic error.
Pressure range limit
The pressure is adjustable within the upper and lower limit.
It is recommended to choose the range code with the lowest pressure range proportion to optimize the
performance specification.
Zero setting
The zero and pressure range could be adjust to any value within the measured rang in the table, only the
calibrated range ≥ Min. Range is valid.
Mounting position effect
The change of mounting position parallel to diaphragm could not influence the zero drift. If the angle
between mounting position and diaphragm is over 90° , the zero drift is <0.25kPa for range C and
<0.15kPa for other ranges which could be calibrated by zero setting. No other effect on pressure range.
Output
2- wire, 4mA~20mA DC, HART communication protocol, linearity or square root output optional.
Output signal limit: Imin=3.9mA,Imax=20.5mA
Response time
The damping constant of amplifier parts is 0.1s, time constant of sensor is 0.1s ~ 1.6s, which is
depended on the pressure range and pressure range proportion. The additional adjustable time constant
is 0.1s~60s.
Warm-up time
< 15s
Environmental temperature
-40ºC~85ºC
With LCD display and viton sealing ring, the temperature is -20ºC~65ºC.
