Features

• MAXITRONIC temperature sensing systems are easy to install and maintenance free.
• Monitors temperatures of each sensor constantly.
• Reduces down time due to a overheating condition.
• Long term savings can be achieved due to increased life of equipment.
• Indicator warning light will illuminate when temperature rises above preset point.
• Silence button is provided to switch internal relay to silence alarm horn.
• Reset button is used to reset circuits - lights and relays when temperature returns to normal condition.
• Test button is depressed to check all circuits for continuity.
• Works in fail safe.
• Maxitronic HB type sensors are UL certified for Class 2 Division 2 Group F&G for use in Hazardous Locations.

Specifications SENSOR ELEMENT: Sensor is a P-T-C (Positive Temperature Coefficient) off-on switching thermistor. SENSOR TEMPERATURE: Customer selects according to need. SENSOR WIRE AND LENGTH: Any 16-28 ga. Copper wire - length up to 5,000 ft. - sensors have no polarity. N/O RELAY: Can be used for external alarm. N/O RELAY: Can be used to shut down equipment when temperature rises above turn on point. RELAY OUTPUT: 7 AMPS. 24 VAC/5 AMPS. 115 VAC. POWER REQUIRED: .5 AMP. 60 HZ/115 VAC.

Because accurate temperature and resistance testing is critical, our PTC manufacturers quality control equipment is constantly calibrated to the National Bureau of Standards. The quality standards are also maintained to meet or exceed the levels set forth by military specifications Q9858.
