Profile: Hydra-Electric Co. is a designer and manufacturer of electromechanical products for pressure, temperature, liquid flow, airspeed and altitude sensing switches. We are an ISO 9001:2000 certified company. Our product line includes pressure & temperature, and liquid flow switches. Our durable gage or absolute pressure switch are ideal for pneumatic, fuel or lube oil system applications. These are suitable for extreme temperature environments. Our temperature switches feature lightweight, miniaturized design, and are used for hydraulic, oil, and fuel system temperature control. Design utilizes a saturated vapor probe thermal system, and a constant modulus negative rate disc spring sensing mechanism to provide quick responses and accurate settings.
