Copal Pressure Indicators


Copal pressure Indicator, 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. Line with customer needs, a business structure that can fine-grained correspondence is also one of the features.

Copal indicator is used in combination with a pressure sensor with an amplifier. The pressure is indicated in the digital form with a voltage input of 1~5 V or a current input of 4~20 mA.
