Mud recording sensor named standpipe pressure sensor

Mud logging sensor called standpipe pressure sensor The pressure sensor can be used to measure the pressure of a viscous, easily blocked medium. As the sensitive component of the sensor adopts a hard membrane structure and does not require a pressure guide cavity, it can resist impact and wear when in direct contact with the measured medium.


MPM489 pressure transmitter is a new pressure transmitter developed by our company. A pressure sensor with a 316L insulated diaphragm is mounted with the high-performance signal processing circuit in the stainless steel housing. The sensor is automatically tested by computer and zero and temperature compensated in a wide range by a laser adjustment system. The digital circuit processes the sensor signal into a standard output signal.


Supply voltage +24VDC ± 4VDC

Output signal 4~20mADC

The range can be customized (0-40MPa).

Nonlinearity ≤±0.5% FS

Hysteresis ≤±0.5% FS

Repeatability ≤±0.5% FS

2-wire wiring system

4-20mA sensor cable

Effect of temperature ≤±0.05%FS/°C

Safety level IEC EEXiaⅡ CT6


The Pump Stroke sensor is an inductive proximity sensor used in the petroleum industry to measure the speed of the pump or turntable. It features a wide range of supply voltages, high repeatability, fast frequency response, long life, vibration resistance, corrosion resistance and water resistance , with polarity and short circuit protection.


The pressure port of MPM489 is a male port with water line seal construction, the electrical connection is plug or connection cable. Compact construction and standard signal output provide you convenience and stability.


All sensors are either EX type or intrinsically safe. Zone barriers are installed in the unit. Through the use of products of well-known brands at home and abroad, the sensors of the sludge logging unit have the advantage of technical and performance indicators. At the same time, the service life is long.


CNPS can ship the goods to you by express, air or sea.


1. Why do you choose our company?

We are a trading company, based on a perfect supply chain of oil and gas equipment products. We have been working in the oil industry for about 10 years (we follow ISO9001) and we check our factories every month to ensure their quality. After-sales service is taken care of by ourselves, allowing us to respond to any problems within 24 hours.

2. How can you guarantee your quality?

Every time, we inspect our factories first. This inspection will include people, current products, their scale, etc. If everything is ok, we will start to cooperate. During the cooperation, we will go to factories to test the products to ensure the good quality of the products. If it does not meet our requirements, the merchandise will be refused.

3. Do you have a price advantage?

For us, quality is our first concern. And the second consideration is price. We can’t say we have the lowest price, because of the quality problem. We have to say we have the best price.

4. How long have you been exporting?

Our salespeople have 8-10 years experience in international trade. They understand every step of exporting and provide good service to each of our customers.
