Range limit
The minimum capacity of a monocrystalline silicon direct-coupled remote pressure/absolute pressure transmitter is the measuring range
The greater of the minimum range of the table and the flange table; The adjustable range must not be small
at the lowest scale.
The maximum range should be the maximum value of the transmitter body and the rated pressure of the remote flange
The minimum of the two.
Response time
The damping constant of the amplifier component is 0.1S, and the sensor and liquid level flange time are constant
The number is: (0.2~6)S, depending on the sensor range, range ratio, capillary size
The length of the tube, as well as the viscosity of the filling solution. Additional adjustable time constants
For: (0.1~60)S
Installation location impact
The intelligent remote pressure/absolute pressure transmitter without capillary can be transmitted remotely
The flange is mounted directly and the position deviation will produce a correctable zero offset.
The electronic case can be rotated up to 360° and the positioning thread holds it in place
What location. Remote pressure/absolute pressure flanges are fitted with ANSI/DIN compliant fittings
The flange is connected, and the matching flange should be equipped with a soft gasket and installed and fixed
bolts and nuts (users can choose to install bolts and nuts). For the band
Capillary intelligent remote pressure/absolute pressure transmitter, if remote sealed device
Lower than the transmitter body, the remote transmission sealing device and the transmitter body are the largest
The height drop should be <5m, when the working pressure is lower than 100kPa absolute pressure,
The transmitter body must be lower than the remote sealing device. Minimal bending of the capillary
The radius is 75mm, and winding is strictly prohibited!
Ambient temperature
The minimum depends on the filling fluid
Up to 85°C
-20~65°C with display and fluoroelastomer seal
Storage temperature
The minimum depends on the filling fluid
Up to 85°C
The temperature limit of the process medium is -30~400°C
