Single Flange Differential Pressure Transmitter

Single Flange Differential Pressure Transmitter has the ability to measure the pressure of a liquid, gas or vapor and convert it to an MADC current signal output of 4 to 20ma. It also communicates with the HART275 communicator for setup, monitoring, etc. It uses advanced micro-processing technology and digital communication technology. In addition to all the features of traditional intelligence, it also has a series of enhancements, such as automatic zero adjustment, remote local control parameter viewing and adjustment of control parameter password lock.

Product description:

Single Flange Differential Pressure Transmitter has the ability to measure the pressure of a liquid, gas or vapor and convert it to an MADC current signal output of 4 to 20ma. It also communicates with the HART275 communicator for setup, monitoring, etc. It uses advanced micro-processing technology and digital communication technology. In addition to all the features of traditional intelligence, it also has a series of enhancements, such as automatic zero adjustment, remote local control parameter viewing and adjustment of control parameter password lock. At the same time, remote parameter setting, remote control, self-diagnosis and other functions are performed through the fieldbus HART protocol. Single Flange Differential Pressure Transmitter has no moving or elastic components, high reliability and low maintenance. Its built-in structure specifically displays this feature without any special tools. Its two potentiometers of zero and span can perform zero offset or range conversion arbitrarily within the effective range of liquid level detection. These two adjustments will not affect each other. Single Flange Differential Pressure Transmitter is suitable for medium level measurement such as high temperature and high pressure and strong corrosion.

HART communication distance: When using multi-core twisted pair, the communication distance can reach 2Km. The pressure transmitter communication distance depends on the cable type. The formula is as follows: L = 65000000 / (R × C) - (C1 10000) / C.

L = length (m and ft)

R = impedance (Ω, including power supply impedance)

C = cable capacitance (pF / m or pF / ft)

C1 = maximum shunt capacitance (pF / m or pF / ft)

A damping time constant flange mounted differential pressure transmitter: the sum of the damping time constants of the amplifier assembly and the bellows. The constant can be adjusted between 0.2 and 64 seconds.
