Description
Differential pressure transmitter is widely used in petroleum, chemical, electric power, metallurgy and other industries. The product is mainly used for measuring liquid, gas, steam differential pressure, pressure and negative pressure can also be measured opening or pressure vessel level, equipped with throttle device can measure the flow of liquid, gas or steam, and the measured parameters into 4 ~ 20mA DC signal output, and passed to the secondary instrument or regulating unit for detection or control. Differential pressure transmitter is suitable for viscous medium at high temperature, easy crystallization medium, precipitating medium with solid particles or suspended matter, strong corrosion or toxic medium, can eliminate the phenomenon of pressure guide pipe leakage pollution of the surrounding environment; Can avoid the use of isolation liquid, because of the instability of the measurement signal, the need to supplement the isolation liquid tedious work. Continuous measurement of interface and density, remote transmission device can avoid the mixing of different instantaneous media, so that the measurement results truly reflect the actual situation of process change. The occasions with high hygiene requirements, such as food, beverage and pharmaceutical industry production, not only require the transmitter contact medium parts to meet the health standards, and should be easy to wash, in order to prevent cross-contamination of different batches of media.
Differential pressure transmitter product features:
1, complete measuring range: 0-0.15kPa ~ 42MPa, a variety of options, flexible application, can meet the needs of most users.
2, small structure, strong, vibration resistance. The integrated terminal box and the zero and range adjustment and LCD display configuration button simplify installation, calibration and operation.
3, in the transmitter housing design of non-contact local zero, range adjustment and LCD liquid crystal display parameter configuration button, easy to adjust the zero and range and set the required field display parameters.
4, solid, plug-in printed circuit board, modular structure, help to troubleshooting and reduce spare parts inventory parameters.
5, adjustable damping, improve the user's selectivity.
6, intelligent circuit, easy to operate.
7, with independent anti-electromagnetic interference circuit and software anti-interference design, improve the reliability of products.
8, the internal temperature parameter sensor, improve the transmitter environmental temperature impact compensation performance, because the sensor and the measured medium direct contact, so at the same time can obtain the temperature information of the medium in contact with the sensor.
9, the transmitter configuration of the field digital display table can directly display the measured pressure value, output analog current value, the measured pressure corresponding to the set range percentage value, the temperature of the sensor body and its contact medium. This technology has been patented.
10, the transmitter improves the fault recovery ability, greatly reducing the transmitter maintenance workload.
11, LCD liquid crystal display table using multi-parameter cyclic display mode.
12, with HART protocol remote communication function, in the realization of pressure measurement at the same time, increase the sensor body and the contact medium temperature detection function, to provide users with more field condition information, conducive to users to improve the effect of process control.
13. The innovative design of the chamber structure of the differential capacitance pressure sensor with an all-metal seal enables significant improvements and good stability in differential pressure (pressure) and temperature measurements.
