ESM2088DPS LCD display differential pressure transmitter for 12-30VDC

The device uses the diffused silicon piezoresistive effect as its core detection principle. Its key component is the diffused silicon sensitive chip, on which four equal-value piezoresistors are fabricated on a single-crystal silicon wafer through semiconductor processes such as ion implantation and thermal diffusion, forming a Wheatstone bridge circuit. When the two pressures of the measured medium (high-pressure end and low-pressure end) act on both sides of the sensitive chip, the chip undergoes slight mechanical deformation due to the pressure difference, causing changes in the resistance of the piezoresistors, which in turn unbalances the Wheatstone bridge and outputs a weak voltage signal proportional to the pressure difference. Subsequently, the signal conditioning circuit inside the transmitter amplifies, filters, and compensates for temperature effects on this weak signal, converting it into a standard electrical signal (such as a 4-20mA DC current signal, 0-5V/1-5V DC voltage signal, or digital RS485 signal), which is ultimately transmitted to a control system (such as PLC or DCS) for real-time monitoring and control of the differential pressure signal.
