Precise Temperature Sensing: HU-225-3-MA-7 NTC Temperature Sensor by MAMAC SystemsThe HU-225-3-MA-7 temperature sensor from MAMAC Systems is an NTC thermistor designed for accurate and reliable temperature measurement in various industrial applications. This high-quality sensor offers precise temperature monitoring with exceptional stability and durability. Featuring a negative temperature coefficient (NTC), this sensor exhibits decreased resistance as temperature increases, providing highly accurate readings over a wide temperature range. Its 2% relative humidity tolerance ensures precise measurements even in humid environments, making it ideal for monitoring temperatures in heating, ventilation, and air conditioning (HVAC) systems. Constructed with durable materials, the HU-225-3-MA-7 temperature sensor can withstand harsh industrial environments. Its 10K Ohm resistance at 25°C ensures reliable operation in a wide range of temperature monitoring applications. Trust our HVAC supply store for your temperature sensing needs, where you'll find exceptional prices and fast shipping!

• Ultra fast response cross-linked bulk polymer capacitive sensing element
• Proprietary hydrophobic and oleopho- bic ePTFE filter to protect the sensing element from condensation, fog, salt air, pollutants and other contaminants 
• Wide 12-40 VDC/12-35 VAC unregulated supply voltage (humidity only)
• Two temperature compensated humidity output versions, 4-20 mA 2-wire or field selectable 0-5 VDC/0-10 VDC
• NIST traceable ±2% RH or ±3% RH cali- bration accuracy and ±0.2°C thermistor interchangeability or ±0.1% RTD accuracy

The HU-225 is an extremely fast, stable and accurate humidity/temperature transducer designed for harsh environments. The polymer humidity capacitance sensor is protected with an ePTFE (expanded Teflon) filter media. The Teflon protected cross-linked capacitive humidity sensor is not affected by prolonged exposure to condensing humidity, harsh environments, contaminants, fog or other extreme environmental conditions. Each unit is individually calibrated in an environmental test chamber to meet or exceed NIST traceable ±2% or ±3% accuracies. The HU-225 is temperature compensated for -30ºF to 130ºF (-35°C to 55°C) operation with negligible error. The HU-225 humidity/temp transducer has an aesthetically appealing ABS enclosure, which may be flush-mounted or fits a 2" by 4" handy box. Field selectable outputs, fully temperature compensated NIST traceable accuracy, non-interacting zero and span adjustments, short circuit and reverse polarity protected output, and a liberal five year warranty are some of the features which make the HU-225 the industry’s highest performance, most reliable humidity/temperature sensor.
