Excelitas’ CaliPile™ thermopile sensors represent the latest innovation in thermal IR sensing. The only one of its kind, CaliPile is an intelligent, multifunction thermal infrared sensor series. In addition to traditional non-contact temperature measurement capabilities, CaliPile offers motion detection and presence monitoring across short to medium ranges… all from a single and compact unit. TPMI has become an industry wide established Excelitas functionality. The CaliPile™ series include specially designed electronic circuitry to provide the algorithm and calibration for temperature measurement, digital output and functionality. This thermopile sensor series provides integrated features that enable measurement as well as presence detection applications. The product line of SMD (surface mount device) thermopiles offer significant space efficiency and streamlined integration. Featuring a thermopile sensor chip connected to internal circuitry within TO packaging with integral lens options, the CaliPile™ sensor TPiS 1T 1086 L5.5 is suited for highly effective, extended-range, multi-function sensing. Equipped with a highly sensitive thermopile detector, onboard processing electronics and a focusing lens for a narrow field-of-view, the TPiS 1T 1086 L5.5 sensor represents the TO housing version of the award-winning CaliPile™ IR Sensor Series. The TPiS 1T 1086 L5.5 is calibrated for temperature ranges up to +350 °C in temperature measurement applications. Higher temperature ranges are optionally available. Users may reference the maximum temperature setting as trigger level since the interrupt function will alert users when the level is exceeded. Featuring a thermopile sensor chip connected to internal circuitry and housed in an ultra-compact SMD package, the CaliPile™ SMD sensor TPiS 1S 1385 is suited for highly effective, near-distance sensing (up to 3 m) without supplemental lensing. This sensor represents Excelitas’ smallest and smartest thermal infrared device to date. To enable these individual functions from a single compact sensor, CaliPile's integrated electronics provide digital conversion and further filtering and processing. The TPiS 1S 1385 is the SMD version of the award-winning CaliPile Series providing I2C bus communication and signal output. An additional interrupt can serve as a ‘Yes/No’ output for the motion, presence and temperature applications. If the application is high remote temperature sensing, we recommend the TPiS 1S 0185 with a higher dynamic range.

Thermistor 10, 20, 50, 100 kΩ; -45 to +114 °C; Bead/Cylindrical Head; ±1%; 76 mm Lead Wires Precision temperature control starts with a precision temperature sensor. Wavelength Electronics’ TCS series of thermistors allows for precise temperature measurements across a wide range of temperatures from -45 °C up to +114 °C. This series of 1% thermistors is available with 10, 20, 50 and 100 kΩ at +25 °C. Most of the TCS series thermistors feature a small bead head (3 x 2 mm) and are conformally coated, two-lead thermistors for applications where embedding the thermistor in materials or small laser packages is required. The coating is baked on phenolic for durability and long-term stability. These thermistors have solid nickel wires with Teflon® insulation to provide isolation when assembled in metal housings. Thermal resistance or dissipation constant is 2 to 3 mW/°C, and the thermal time constant is 6 to 14 s. The TCS10K5 model features a cylindrical size of 0.5 x 3 mm, encapsulated in a polyimide tube with 38 AWG nickel bifilar leads - ideal for tight mounting spaces, assemblies where surface mounting or embedding the thermistor is required, and applications like controlling optical surfaces, thin surfaces or small laser packages. Thermal resistance or dissipation constant for TCS10K5 is 0.2 mW/°C, and the thermal time constant is 200 ms. A complete resistance vs. temperature chart is included in the datasheet. The TCS series thermistors are sold in packs of 10 (5 for TCS10K5). For a given thermistor, to accurately measure the voltage (which is related to the temperature), a bias current must be provided. Since the resistance of a thermistor varies as temperature changes, the bias current must be stable and consistent. In general, there are two commercially available bias current ranges, 10 or 100 µA. Choose the bias current and thermistor combination such that the sensor voltage remains above 0.3 V for the temperature range under consideration. When the sensor voltage falls below 0.3 V, the sensitivity of the measurement is decreased. For more information, see Application Note “Calibration Coefficients and Thermistor Selection”. For optimum performance, system operating temperature should fall in the middle of the thermistor operating range, and within a single bias current range.

Fire and Overheat Detection: IR Thermopiles, more specifically multi-pixel sensors, when integrated with a smoke detector, help to detect hot spots in a room. An emerging application is thermopile arrays combined with a surveillance camera to detect indoor or outdoor fires. Similarly, these sensors are also used in cooking ranges to monitor oven temperature and provide overheating protection. Elevated Skin Temperature (EST) Screening: A 2-dimensional (4 x 4 pixel) array is preferred for use in measuring temperature distribution of the facial skin temperature for fixed installations or portable equipment.
