Thermopile Sensor Application Circuit

Thermopile sensors application note te connectivity sensors an thermopile sensor page 10 2018 4 reference sensor the reference sensor is used to measure the temperature of the sensor.

Thermopile sensor application circuit.

It is needed according the formula describing the thermopile voltage in figure 1. Energy water gas monitoring of power station search for fluid leaks control of storage reservoirs detection of occupants in room materials control of chimney stacks. Heimann thermopile modules are non contact thermometers comprising a high sensitive thermopile sensor and a signal conditioning circuit in the same housing. The thermopile sensor consists of a series of 116 thermoelements forming a sensitive region size of 545 µm diameter.

A thermopile is a device that converts thermal energy into electrical voltage. Thermopile infrared ir non contact temperature measurement sensors are available with various lens and filters allowing use in multiple applications from industrial pyrometers to climate controls and medical devices. A reference sensor is designed into the package as a reference for compensation. It provided very high performance in the circuit.

Commercial thermocouples are inexpensive interchangeable. To reach enough accuracy a reference sensor in a thermopile component must be. The following typical applications will help you when selecting the type of thermopile sensor. R2 5v a1 a3 a2 adder vout c3 r9 r8 c2 thermopile thermopile r1 r7 c1 2 4 r13 r10 r11 r12 5v c4 reference.

Application circuit circuit 1. There are lots of cool applications they can be used for including motion sensors temperature probes fire alarms heat flow detectors robot sensors forge temperature monitors or low resolution thermal. Thermopile detector for the desired device and performance. It s what you find in those in ear infrared thermometers or remote temperature probes used in the food industry.

The thermopile modules can be supplied factory calibrated to a defined object temperature range with or without internal temperature compensation reducing ambient temperature influence or. The sensor is hermetically sealed into a to 5 metal. The circuit was designed at least a decade ago and used the opa335 auto zero op amp. The thermopile sensor converts the temperature radiation of an object surface to an electrical.

For starters take a look at a thermopile amplifier design that was developed by neil albaugh who used by an applications engineer in this department for many years.
