日本語Oil level gauge & relay and Temperature relay are working at hydroelectric power stations. Differential pressure regulator and Oil relief valve are used with seal oil system at thermal power stations.
Oil level gauge & relay
This product is designed as the micro switch makes or brakes by the up-and-down of a float moving according to oil level.
It is used for oil level control of cooling device for the bearing of the waterwheel generator shaft.

Liquid filling pressure type thermometer
The insides of the thermo-sensor cylinder, capillary, and Bourdon tube are filled with liquid which changes volume with varying temperature. Since the displacement of the Bourdon tube due to an internal pressure change is directly indicated on the scale division plate, this product is excellent in vibration resistance.

Oil relief valve
This product is used in the sealing oil unit of the hydrogen cooling type generator in power stations operated by combined cycle method, and to prevent pressurization to the oil flow inlet of the Differential pressure regulator keeping the pressure at the oil pump discharge port at an optional fixed value.

Pressure Gauge for OF cable
This product is a pressure gauge with alarm contacts for oil regulating tank, which is used for the OF cable for ultra-high voltage power transmission. This pressure gauge indicates the pressure of insulating oil or insulating gas in the cable, and outputs an alarm when the pressure exceeds the specified range.
