Sensors, temperature probes, water pressure switches, replacement batteries and more for remote barn monitoring/alarm systems such as Sensaphone, Farm Alarm and more.
The 20P-30 Pressure Swichgage® is a 2" dial, diaphragm-actuated pressure-indicating gage with a built-in electrical limit switch, which is used for tripping alarms and/or shutdown devices.
The 20P-75 Pressure Swichgage® is a 2" dial, diaphragm-actuated pressure-indicating gage with a built-in electrical limit switch, which is used for tripping alarms and/or shutdown devices.
The ThermAlarm II is well-suited to applications requiring a narrow high-low temperature range, or where recurring temperature fluctuations of only a few degrees must be sensed.
When the temperature exceeds your settings the sensor triggers an alarm. It requires no power for operation and multiple units may be wired in series to a single input.
