Liquid Level Pressure Controller with Relays Output Signal

Instruction:
HPC-1000 product is the intelligent display pressure controller combining with pressure measure, display and control together. The product is full electronics construction. The front part uses piezoresistive pressuresensor with isolated diaphragm as the sensing element, sensor output signal is amplified by high accurate andlow temperature drift circuit, transferring into A/D convertor and transforming into digital signal. The processed signal controls two relays and then measure and monitor pressure. The product is used flexibly and easily calibrated, can be used for pressure measure, display and control for power station, tap water, petroleum, chemi-industry, engineer and liquid pressure, ect.
