UPB3-b LOW COST compact pressure transmitter
UPB3-b compact pressure transmitter is made integrated structure by using high quality thick-film ceramic sensors and special amplified circuits. The output of UPB3-b is configured to 4~20mA current loop, or 0~5Vdc, or 0~10Vdc, or 1~5Vdc voltage signals. The pressure diaphragm of this transmitter is made from ceramic material, while its wetted parts is made from 316L stainless steel. Because of the thermal stability of ceramic and its thick-film resistance, the transmitter can be operated in a higher temperature range; at the same time, this also makes the zero & sensitivity thermal shifts over the whole operating temperature range of the transmitter is very small.
The compensated temperature range of UPB3-b is 0~70°C, UPB3-b is designed for use in most industrial application, and this product is suitable for measurement of most pressure medium (including corrosive medium) directly.
Features:
*Wide application scope and long service life
*Automatic testing and laser trimming compensating zero & sensitivity
*High accuracy & long-term stability
*Good ability on anti-corrosion & anti-impact
