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.
Thermopile sensor application circuit.
Heimann thermopile modules are non contact thermometers comprising a high sensitive thermopile sensor and a signal conditioning circuit in the same housing.
Application hints temperature calculation and compensation the heimann sensor integrated module htia consists of a fast response thermopile sensor and an asic as specific integrated circuit for the signal processing and on chip calibration.
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.
The thermopile sensor converts the temperature radiation of an object surface to an electrical.
Thermopile detector for the desired device and performance.
A thermopile is a device that converts thermal energy into electrical voltage.
The circuit was designed at least a decade ago and used the opa335 auto zero op amp.
A reference sensor is designed into the package as a reference for compensation.
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.
The sensor is hermetically sealed into a to 5 metal.
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.
It s what you find in those in ear infrared thermometers or remote temperature probes used in the food industry.
It provided very high performance in the circuit.
Commercial thermocouples are inexpensive interchangeable.
The thermopile sensor consists of a series of 116 thermoelements forming a sensitive region size of 545 µm diameter.
A thermopile is an electronic device that converts thermal energy into electrical energy it is composed of several thermocouples connected usually in series or less commonly in parallel such a device works on the principle of the thermoelectric effect i e generating a voltage when its dissimilar metals thermocouples are exposed to a temperature difference.
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.
A thermocouple is an electrical device consisting of two dissimilar electrical conductors forming an electrical junction a thermocouple produces a temperature dependent voltage as a result of the thermoelectric effect and this voltage can be interpreted to measure temperature thermocouples are a widely used type of temperature sensor.
The following typical applications will help you when selecting the type of thermopile sensor.
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.
