Temperature level float switches provide the ability to incorporate temperature sensing and liquid level detection into one convenient sensor. The temperature sensing device is a bi-metallic thermostat that is designed as general protection for heaters or to warn of high or low temperature conditions, they are not intended to act as precision temperature indicators. Both temperature and float level can be ordered either normally open or normally closed.
Thermowell Sensors are designed to indicate temperature only. These small probes can fit into almost any size tank. The most common temperature sensing devices are thermostats, thermistors, thermocouples, and RTD’s. Bi-Metallic thermostats provide a gross high or low temp cut off or warning. The thermistors, thermocouples, and RTD’s are high precision sensing elements that give very accurate readings of the exact temperature of the liquid.
