XG3051T Differential pressure/absolute pressure remote transmitter

Product Introduction：
XG3051T intelligent remote pressure transmitter supports measuring gauge pressure and absolute pressure. It adopts a remote transmission capillary membrane isolation structure to isolate the measured medium from the transmitter body. It can cope with high viscosity, easy crystallization, easy solidification, strong corrosion, and high-temperature medium working conditions, preventing medium blockage and corrosion of sensors.
Output 4-20mA superimposed HART protocol digital signal, high accuracy, good long-term stability, supports on-site configuration calibration, optional on-site LCD, with explosion-proof protection, customizable diaphragm material, realizing long-distance transmission of pressure signals.

Applicable industries:
1. Petrochemical industry: pressure measurement of reaction vessels and storage tanks
2. Electricity: Boiler and heat pipe network pressure monitoring
3. Metallurgy: Pressure detection in the smelting process
4. Water treatment: sewage and chemical water treatment tank pressure
5. Pharmaceutical: Pressure control of pharmaceutical process tanks
6. Food and beverage: pressure measurement of viscous materials
7. Coal chemical industry: pressure detection of various process equipment
8. Paper making: pressure collection of pulp media

FAQ Input Output Response Time General Conditions Electrical Connections Model and Specification Code Table Dimensions
Q1: What operating conditions is the XG3051T remote transmitter suitable for?
A: Suitable for high viscosity, easy crystallization, easy solidification, strong corrosion, and high-temperature media. Through remote transmission membrane and capillary isolation, the medium is prevented from directly entering the transmitter body, preventing blockage and corrosion of the sensor. It supports two measurement modes: gauge pressure and absolute pressure.

Q2: How to choose between gauge pressure and absolute pressure?
A: Select gauge pressure for measuring relative atmospheric pressure. When measuring vacuum and negative pressure, absolute pressure should be selected as the reference for the working condition, and cannot be mixed; otherwise, there will be significant measurement errors.

Q3: What is the output signal? Can I connect to a HART handheld device?
A: Standard 4-20mA analog output, combined with HART digital protocol, supports on-site configuration, range modification, zero point calibration of HART controller, and can be connected to DCS and PLC systems.

Q4: How to choose the material for remote transmission film?
A: Conventional 316L stainless steel; for strong corrosive media, Hastelloy alloy and tantalum film can be selected, and the composition and temperature of the media can be provided when ordering.

Measurement parameters: gauge pressure, exothermic pressure, liquid level.

The damping constant of the amplifier component is 0.1 s; the time constant of the sensor and remote seal flange ranges from 0.2 ~ 6 s, depending on the sensor range, range ratio, capillary length, and viscosity of the fill fluid.
The additional adjustable time constant ranges from 0.1 ~ 60 s.

Installation Conditions
Gauge / absolute pressure remote transmitters without capillary tubes can be mounted directly via the remote flange. Position deviation will cause a correctable zero shift. The electronics housing can rotate up to 360°, and the set screw can secure it in any position.

The gauge / absolute pressure remote flange connects to mating flanges complying with ANSI/DIN standards. Such mating flanges shall be equipped with soft gaskets and mounting bolts and nuts (bolts and nuts are optional for users).

For gauge / absolute pressure remote transmitters with capillary tubes: if the remote seal assembly is installed below the transmitter body, the maximum height difference between the remote seal assembly and transmitter body shall be less than 5 m. When the operating pressure is below 100 kPa absolute, install the transmitter body below the remote seal assembly.

The minimum bending radius of the capillary tube is 75 mm. No coiling is allowed!
