Optris OPTCTLT25F CTfast LT25F Infrared Thermometer for Extremely Quick Temperature Measurements
Overview
The Optris CTfast LT25F Infrared Thermometer is perfectly suited for especially quick non-contact temperature measurements. Due to its extremely short response time of 6 ms. The unchoppered sensor allows a continuous temperature surveillance of fast processes in a spectrum of -58°F to 1787°F (-50°C up to 975°C). With a Spot Size (Optical resolution) (90 % energy) of 25:1 and rugged sensor head that can be used up to 248°F (120°C) ambient temperature without cooling.Features
- Temperature Range -58 °F to 1787°F (-50°C to 975°C) scalable via programming keys or optional USB, RS232, interface and software
- High Optic Resolution of 25:1
- Spectral response 8 to 14µm
- Continuous process monitoring with an unchoppered sensor system
Note: Conventional fast pyroelectrical infrared sensors with mechanical chopper see processes only part of the time - Instant digital 0/10 V output with a response time of 4 ms (50 % signal)
- Ambient temperature sensor head rugged and usable up to 248°F (120°C) ambient temperature without cooling
- Separate electronics housing with easy accessible programming keys and LCD backlit display
- IP 65 (NEMA-4) Sensing Head and Electronic Housing
- Emissivity 0.100 to 1.000 adjustable via programming keys and LCD backlit display
- Signal processing: Peak Hold, Valley Hold, Average; Extended hold function with Threshold and Hysteresis
- Scalable analog output: 0/4 to 20mA, 0 to 5V, 0 to 10 V, or Thermocouple Type K or J
- Optional USB, RS485, RS232 interface, relay outputs (2 x optically isolated)
