■ Product Overview

The ERS Series industrial pressure transmitters are manufactured using a piezoresistive silicon sensor with all stainless steel construction.

Designed and produced using advanced precision electronic component manufacturing technology and PCB chip design technology, these transmitters undergo strict process and quality control procedures, including testing for noise immunity, burst pressure resistance, insulation performance, and surge protection. Every unit is individually calibrated prior to shipment to ensure reliable performance and accuracy.

The ERS.308 pressure transmitter supports both Modbus RTU digital communication via an RS485 interface and analog outputs (4…20 mA / 0…10 V / 0…5 V / 1…5 V) simultaneously. This makes it an ideal solution for industrial applications requiring both digital communication and analog signal output.

■ Applications

▶ Hydraulic and pneumatic control systems

▶ Pumps and compressors

▶ Control equipment and HVAC systems

▶ Pressure monitoring systems

▶ Petroleum and chemical industries

▶ Automated manufacturing processes

▶ Heavy industry and shipbuilding

▶ Wastewater and water treatment industries

Depending on the application requirements, specially designed diaphragm seals, chemical seals, or process flanges can be added to ensure optimal and efficient operation.
