TEMPERATURE SENSOR ASSEMBLIES (PROBE)

Transcription

1 Discription: TEMPERATURE SENSORS A temperature sensor is an element that sensed the temperature changes, then translate the measured temperature into an electrical signal which then providing the data to the electric controller or switch. The controller or switch takes the signal to interpreted a circuit. There are several aspect to consider when you chose a temperature sensor for your applications. Such as low and high temperature in the measuring media, working environment NTC Thermistor( Negative Temperature Coeffient) & NTC Assemblies PTC Thermistor(Positive Temperature Coeffient) & PTC Assemblies DS 18B20 in 2-wire, 3-wire & 4-wire (duplex) version PT (Platinum Resistance Temperature Sensor) Temperature Switches RTD (Resistive Temperature Detector) Thermistors TEMPERATURE SWITCH A temperature switch is an element that is responsive to temperature changes. Temperature switches equip with a integrated temperature sensor which acquire the temperature of the power switch and convert this into a temperature dependent, analog signal which then can be interpreted in a circuit. Temperature sensitive switches, such as a thermostat, typically comprise a temperature sensor which is used to open or close electrical contacts at specified temperatures. A bimetal strip is used as the sensing element for temperature sensitive switches. Temperature sensitive switches are often used for thermal protection purposes. The commonly used toaster which equipped temperature sensor and switch. The switch will turn OFF the electricity once the toaster get to the desired temperature. Other most commonly used temperature responsive tip-switches are particularly useful in connection with electric heaters. When temperature sensing device gets too hot, the switch will opens the electrical circuit to eliminate power to the heater. (a thermistor is connected with a lead and sealed in a probe or a housing) TEMPERATURE SENSOR ASSEMBLIES (PROBE) Temperature sensor assemblies is the construction of a thermistor connected with a lead wire sealed in a housing or probe to create an easy exchangeable or removable independent part which can be easily removed or exchanged in a working process without shut down the process. The endless assembly combination would meet any industry field needs. For example, a threaded probe can be easily thread in and out into a thermowell which permanently connected into the process to measure the media temperature.
