2455R71001002

Temperature Sensors are a critical part of a wide variety of applications, such as industrial and commercial heating, ventilation and air conditioning (HVAC) systems. The 2455R71001002 is a type of Temperature Sensor that uses a mechanical thermostat, which works in a manner analogous to domestic thermostats. The sensor has the ability to accurately measure and monitor temperatures in temperatures between -50°C and 80°C (-58°F and 176°F) and is suitable for use in hazardous locations.

A mechanical thermostat is a device that contains an internal switch which is connected to a mechanical spring. When the temperature of the environment rises above a preset level, this spring compresses, closing the internal switch and thereby creating an electrical contact. This contact indicates that the temperature has exceeded the preset level.

These kinds of Temperature Sensors are widely available in both single-pole double-throw (SPDT) and double-pole double-throw (DPDT) variants. The DPDT variety provides redundancy as two sets of contacts are available which can be used to detect both low and high temperatures. The 2455R71001002 specifically is a DPDT type with an adjustable actuation temperature of between -30°C and 80°C (-22°F and 176°F). It has a relatively low operating current of 3.5mA and a maximum current rating of 38mA at 25°C (77°F).

Mounting the 2455R71001002 can be achieved easily by using either twisted-pair or solid-core temperature sensing wire. The wiring should be kept at least 25cm (10in) away from any power cables and should not be exposed to any heat or flame. The temperature sensing wire should be connected to the two external leads of the sensor: one red or yellow lead and one blue. Care should be taken to ensure that the red/yellow lead is always connected to the higher temperature end of the sensing wire.

The 2455R71001002 is widely used in industrial and commercial applications. It is especially suitable for uses in hazardous locations as it has an ingress protection rating of IP68, meaning it is impervious to dust and can remain submersed in water up to a maximum depth of 40 metres (131 feet) for up to three hours. The device also has a superb operating life of up to 10 million cycles.

The 2455R71001002 is easy to install and is ideal for use in both industrial and commercial settings. Its adjustable actuation temperature makes it suitable for a variety of applications, from monitoring the temperature of air conditioners to detecting overheating of machinery. Its high ingress protection rating and long operating life of up to 10 million cycles make it an excellent choice for applications where reliability is essential.
