761-2A-44A Bestace -2.5/+2.5kPa 12-32VDC Differential Pressure Transmitter

Description

Bestace 761-2A-44A is a high-precision differential pressure transmitter featuring a -2.5 to +2.5 kPa measurement range, 12 to 32 VDC power supply, and a 4 to 20 mA output signal (12 ± 8 mA). The unit utilizes a piezoresistive silicon sensing element housed in a rugged die-cast aluminum alloy enclosure with 316L stainless steel wetted parts. It incorporates internal signal conditioning circuitry to provide a linear output proportional to the applied differential pressure. The mechanical interface consists of dual pressure ports for high and low-side connections, ensuring stable performance under fluctuating static pressures. The device is designed with an IP65 protection rating and features a terminal block electrical interface for secure industrial wiring.
