Our Best-Selling Pressure Sensor
Electronic Pressure Sensor
The electronic pressure transmitter, a device that converts pressure into electronic signals, can convert the physical pressure parameters of gases, liquids, etc. measured by pressure measuring elements into standard electrical signals, which are then supplied to secondary instruments including alarm indicators, recorders, regulators for measurement, indication, and process adjustment.
Valve Position Shifter
The valve position transmitter is used in conjunction with the throttle manifold control box to display the hydraulic throttle valve opening/closing position on the operation panel, enabling operators to monitor and control the working status of the throttle manifold in real time.
Pneumatic Pressure Transmitter
Pneumatic shock resistant pressure transmitter is a device that can convert high pressure in pipelines into LP pressure signals, used for pressure detection in harsh environments. It can be used in conjunction with the choke manifold control panel to achieve real-time monitoring for mud pressure in casing and standpipe, which is particularly important in oil drilling operations because it can help operators timely know about the downhole pressure situation to take corresponding measures to ensure the safety of drilling operations.
Hydraulic Pressure Transmitter
The vibration-proof pressure sensor is used in conjunction with the throttle manifold control box and uses hydraulic oil as transmission medium. On the panel of the control box, the standpipe pressure, casing pressure, and hydraulic throttle valve opening/closing position can be displayed, and besides, by equipping the pump stoke counter, the number of strokes and stroke frequency of the three mud pumps can also be displayed separately, all of which are crucial for maintaining the balance of bottomhole pressure. It is a necessary equipment for successfully controlling well surges and blowouts.

How to Calibrate a Pressure Sensor
To determine whether the wiring is correct, the transmitter has a current (two-wire), voltage (three-wire) output.
The specific adjustment: A zero point correction of the transmitter B pressurized calibration, the actual calibration weight value / display value = FC full scale correction (0-1.5).
Regular pressurization and return to zero Check the sensor linearity and repeatability to determine the stability of the sensor.
Guidelines for Installation of Pressure Sensor
Install the transmitter with proper support.
01
Use proper cable.
02
Keep corrosive & hot process material away from the transmitter.
03
Keep impulse piping as short as possible.
04
Keep minimum joints, bends in impulse piping.
05
Keep liquid head balance at both the sides of transmitter.
06
Avoid sediment deposits in the impulse piping.
07
Avoid ambient temperature gradient and fluctuations.
08
Check for any leaks in the system.
09
Provide insulation if necessary.
