ZTP-115
Thermopile Infrared (IR)
Sensor
Thermometrics Thermopile Infrared (IR)
Sensors are used for non-contact surface
temperature measurement. The ZTP-115 Model
consists of thermo-elements, at IR lter, and
a thermistor for temperature compensation
in a hermetically-sealed small-size package.
Various lters are also available to maximize
performance in specic applications.
Applications
• Patient monitoring
• Ear & Tympanic thermometers
• Occupancy detection
• HVAC
• Appliance
Features
• Non-contact measurement
• Wider surface area measurement
• Small-size sensor package
• Included ambient temperature (thermistor)
sensor for compensation
• High sensitivity
• Fast response time
• Low cost
• RoHS compliant
