Cannon Technologies Sensors are the result of our perceived need for monitoring applications that required sensors which did not exist or were not easy to retrofit. Our solution was to design our own inexpensive, hardened, sensors appropriate for substation retrofit.

These sensors can be used with any SCADA RTU, and are available “ala carte”.

Substation Sensor Order Form

	AC Current Sensor - Use the AC Current Status Sensor (ACST) to monitor the presence of AC current in a conductor. Example applications include monitoring of transformer fan motors, oil pump motors, circuit breaker air compressor motors, spring charging motors, LTC mechanisms, and SF6 tank heaters.
	DC Current Sensor - Use the DC Current Initiate Sensor (DCIS) to monitor and indicate the initial rising edge of DC current in a conductor. Example applications include Sequence of Events (SOE) logging and timer applications for trip currents, relay operations, and breaker operations.
	TSS/TSA Temperature Sensors - Use model TSS Temperature Sensors to measure a device’s surface temperature. Typical applications include transformer LTC tanks and transformer main tanks. Use model TSA Temperature Sensors to measure ambient air temperatures.
	PS1 Pressure Sensor - The model PS1 pressure sensor is used to measure the pressure of enclosed gas systems. It can be used, with fittings engineered for specific equipment to measure the pressure of a transformer tank, SF6 insulating gas, or a pneumatic circuit breaker air tank.
	TSP Temperature Oil Probe - The model TSP temperature probe replaces a transformer's existing top oil temperature indicator and provides a means to measure the oil temperature via SCADA.
