Function parameter

Range limit
	Within the upper and lower limits of the range, it can be set arbitrarily,Just make calibrate the range≥set range, It is recommended to select a range with the lowest possible turndown ratio to optimize performance.
Installation position influence
	Changes in the installation position perpendicular to the diaphragm surface will not cause zero drift,If the installation position and the diaphragm surface change more than 90°,Null effects in the range < 0.4kPa will occur,It can be corrected by zero adjustment, no span influence.
Output Signal
	4~20mA+HART protocol digital signal
	RS485 Serial signal
Alarm current
offline	3.6mA
online	21mA
failure warning
	If a sensor or circuit fails,Automatic diagnosis function automatic output 22.0mA
Response time
The damping constant of the amplifier part is 0.1S,The sensor time constant is:(0.1~1.6)S,depends on turndown and turndown ratio.The additional adjustable time constant is:(0.1~60)S. The effect on non-linear output (such as a square root function) depends on the function,and can be calculated accordingly.
Preheat time
	<15S
