Air-gas/surface. NTC. Phenolic thermostat-type package.
The 6655 Series On-Surface Temperature Sensors are lower cost, thermistor-based temperature sensors that use Honeywell’s compact, low-profile, 12,70 mm [0.5 in] thermostat package. These products are 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 has gained widespread acceptance standard due to their robust design and ease of installation. A variety of mounting brackets provides mounting flexibility.
