Product specifications

MPT921 type strain type high pressure pressure sensor is a new product which integrates the advanced technology and the technology of the domestic sensor. The sensor adopts import high-precision resistance strain meter and domestic unique variable thickness sheet technique, the measurement range of up to 120MPa and has high response and high accuracy, firm structure, corrosion resistance, anti vibration, high performance price ratio and so on. The transmitter is built in anti - interference amplifier circuit, which is suitable for the signal output under complex conditions. The product uses a spherical seal, easy to install, easy to use, suitable for all kinds of exploration and exploitation. High voltage measurement is widely used in oil drilling equipment in the industry, in particular, imports of fracturing truck, cementing vehicles, alternative American Vtron, Dowell, Stevenson - History of Tivat, Henry Ward Beecher, various types of imported fracturing car sensor.
