SPB2088 Diffuse silicon pressure transmitterDetailed product description：

The SPB2088 diffusion silicon pressure transmitter uses imported pressure chips, and the sensitive components are formed by diffusion or ion implantation processes to form resistors and connected into a Wheatstone bridge. Micro mechanical processing technology is used to form a pressure sensitive diaphragm under the bridge. When pressure is applied to the diaphragm, the resistance value changes and a linearized output signal proportional to the applied pressure is generated. We add a DC power supply to the Wheatstone bridge, which produces an output of a DC voltage signal. After a secondary conversion circuit, achieve a two-wire 4-20mA output.

Features:
Good stability, with a long-term stability of 0.2% FS/year at full and zero positions. Within the compensation temperature range of 0-70 ℃, the temperature drift is less than 0.2% FS, and within the entire allowable operating temperature range, it is less than 0.5% FS.
Equipped with reverse protection and current limiting protection circuits, the transmitter will not be damaged if the positive and negative poles are reversed during installation. In case of abnormalities, the transmitter will automatically limit the current to within 35MA.
Solid state structure, no movable parts, high reliability, long service life
From wind pressure to water and oil, high-precision measurements can be made without being affected by the mass of the measured medium.
Easy to install, simple structure, economical and durable.
