Digital Pressure gauge

Copal Digital Pressure Gauge, integrated production in-house from the semiconductor sensor elements to the final products. To Amp. built-in type from the module type, and even boasts a rich line-up such as the type which includes a switch function and indicators. In line with customer needs, a business structure that can fine-grained correspondence is also one of the features.

The PG series Copal Digital Pressure Gauge  are pressure gauges composed of a semiconductor-type pressure sensor, electronic circuits, and a display that measures pressure and displays the pressure in the digital/numerical value. The option includes those with a pressure switch function and an analog output function. The pressure setting for the pressure switch can be made by looking at the digital pressure display.
