A Bolometer.
The scientific name for the receptors of heat is THERMORECEPTOR which is one of catogories of Touch receptor. THERMORECEPTORS are sensitive to change in temperature.
An elevator shunt trip test checks the heat detector placement. It also monitors power and wiring diagram of an elevator.
A flame detector is a fire protection device, which detects the flame in the place where it is fixed and issues an alarm thereby alerting nearby people to the danger of fire. In most of the manufacturing companies, furnace flame detector is used in order to detect and prevent fire. Flame detector responds either to radiant energy visible to the human eye or outside the range of human vision. Most flame detectors work either by optical flame detector or flame ionization detector but some of them use combination of both detectors.Flame detector works at specific ranges, which uses optical sensors to record the incoming radiation at a particular wavelength. The energy radiated from the flame is electromagnetic radiation and it can be identified at various spectral ranges like UV, IR and VIS. Depending upon the sensor used there are number of flame detectors available they are infra red flame detectors, ultra violet flame detector, UV/IR, IR/IR and tripe IR spectral band detector. Flame detector has a cone of vision that defines the effective capability of sensing fire. It is inefficient for slow fires however it responds faster for rapidly developing fire like combustible gas and liquid. It is available in different shape and size.

there are 3 detectors i can only think of 2 off the top of my head, there is a continuous fire wire which detects mainly heat and sets off the sensor if there is a break in the wire caused by melting,, so u may get a false fire indication from a hot start, there is also an infra-red detector which is more accurate as it can be used to detect actual flames,, the third detector is much like the continuos fire wire and only detects heat so again is not as accurate as the infra red.
To use the PLL (Phase Lock Loop) as FM detector, you need to know the Free-running frequency.
A heat detector is connected to a fire alarm system. It is designed to respond when the heat sensitive element has increased temperature due to a fire.
According to radardetectors.com, the Valentine is the most sensitive and most highly rated of all the radar detectors. It provides front and rear detection.
This type of smoke detector is more sensitive. It uses a laser diode in the sensor instead of an LED which allows it to be much more sensitive.
5M Detector to Detector
Chances are your smoke detector is faulty and needs to be replaced . They are very sensitive and break very easy. But most likely your detector got damaged when you changed the batterys.
none ya business
The Ademco Wireless Heat Detector is an essential element to any home. Detecting temperatures of 135 degrees or above, this ultra-sensitive heat detector alerts home occupants of any impending danger. This particular sensor also alerts inhabitants if the temperature rises 15 degrees or higher per minute. This easy to install detector is perfect for difficult to wire sections of the house, instantly noticing occupants of any danger. The Ademco Heat Detector features a tamper switch, is powered by a three volt lithium battery, and contains a built in transmitter, alerting the system's control unit of any battery malfunction.
I am not personally familiar with the ademco heat detector, but I have done some research and have found that this head detector is pet immune, and pets do not cause interference with this heat detector security system.
first optical smoke / heat detector to second optical smoke/heat detector maximum distance.
A heat detector is a good addition to the smoke alarm. It will help to detect a heat source that is growing in case the smoke alarm in the home is not functioning.
no
Then it wouldn't be a smoke detector, but there are fire alarms that are triggered by temperature.
