6655 Series On-Surface Temperature Sensors DESCRIPTION The 6655 Series On-Surface Temperature Sensors are lowercost, thermistor-based temperature sensors that use Honeywell's compact, low-profile, 12,70 mm [0.5 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 your needs. A wide operating temperature range of -20 C to 110 C [-4 F to 230 F] allows application flexibility. The 6655 Series products have gained widespread acceptance standard due to their robust design and ease of installation. A variety of mounting brackets provides mounting flexibility. FEATURES POTENTIAL APPLICATIONS * Air/surface temperature sensing * Water heaters and boilers * NTC thermistor output * Industrial ovens and ranges * Low cost * Copier diffuser rollers * Low, compact profile * HVAC compressor or duct temperature sensing * Tight interchangeability * Enhanced accuracy * Enhanced response time * Wide operating temperature range * Variety of mounting brackets * Widely used sensor package footprint * Enhanced stability/low drift 6655 Series Table 1.
