Technical parameters
Medium: liquid, gas or steam
Measuring range: 0~0.12KPa/ 0~40MPa
Output signal: 4~20 mA DC
Power supply: 12~45VDC,( ordinary 24VDC as usual) see load characteristic diagram
Load characteristic:
It is related to the power supply. The load capacity at a certain power supply voltage is shown in the figure. The relationship between the load impedance(RL) and the power supply voltage(Vs) is RL≤ 50(Vs-12)

Product Parameters

Temperature influence( Max. Range)

Type	Standard
Max. Range temperature drift	≤1.5%/60ºC	≤2.0%/60ºC
Min.range temperature drift	≤3.5%/60ºC	≤5.5%/60ºC

 Static pressure influence( Max. Range)

Operating pressure(MPa)	Operating pressure error(Max. Range)% FS
	Range code	1	2	3	4	5	6	7
Max.range temperature drift		±0.5	±0.5	±0.5	±0.35		±0.65
Min.range temperature drift					±0.65		±1.25

Vibration influence
When vibration frequency is 200Hz, the error is ±0.05%g of upper limit of the measuring range.
Power supply influence
Less than 0.005%V of the output range
Overload influence
If the power supply is stable and overload will have no influence
Installation direction influence
Max may exists 0.24KPa of zero error, but it can calibrate and no influence to the range.
