Hydraulic Pressure Transmitter

The shock resistant pressure transmitter is used with the choke manifold control panel and uses hydraulic oil as the transmission medium. On the panel of the control box, the standpipe pressure, casing pressure, and hydraulic throttle valve opening/closing position can be displayed. Besides, by equipping the pump stroke 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 necessary equipment for successfully controlling well surges and blowouts.

The vibration-proof pressure transmitter can transmit the mud pressure in the casing/standpipe to the pressure gauge on the panel of control box for display through the transmission medium hydraulic oil. This sensor is a variable ratio sensor, which has the advantages of high accuracy, easy installation, strong durability, excellent anti-interference and anti-vibration performance, and natural blast resistance, and it can be used for pressure monitoring in various harsh environments.

Product naming rules and selection

Technical parameters

Applicable Scenarios

Wellhead safety valve control, high-pressure hydraulic system monitoring.

Core Advantages 

1. Ultra-High Pressure Coverage

Supports a pressure range of 35MPa~140MPa, meeting the demands of deep-sea oil & gas wells and high-pressure pipelines.

2. Corrosion Resistance and Temperature Tolerance

Key components made of 316SS stainless steel, suitable for -29℃~+82℃ wide temperature environments, resistant to oil & gas corrosion and high-pressure conditions.

3. Deep Integration with ESD System

Directly participates in the automatic closure logic of ground safety valves through hydraulic signals, with a response time of milliseconds.

4. Redundancy Design for Reliability

Employs "two-out-of-two" or "three-out-of-two" voting mechanisms to ensure system safety in case of single-point failures.
