Overview

6655 Series on-surface temperature sensor, NTC, 10,000 Ohm, ±10.0 % tolerance, 3976 BETA, 16 R-T curve, phenolic, bracket (fixed surface), quick connect terminal [90°, 0.1875 in].
The 6655 Series on-surface temperature sensors are lower-cost, thermistor-based temperature sensors that use Honeywell's compact, low-profile, 12,7 mm [0.50 in] thermostat package. This series is designed to offer temperature measurements with enhanced response and accuracy on most flat surfaces and pipes in non-condensing applications. Unlike thermostats, which are generally limited to one fixed temperature, these thermistor-based NTC (Negative Temperature Coefficient) devices allow the customer greater flexibility in temperature monitoring and controlling. Tight interchangeability eliminates or reduces customer need for calibration. Enhanced accuracy and response time are designed to meet customer needs.
