HU-225-2-VDC-17 | Temp & RH 2% | Temp: 20K | RH: 0-10VDC | Room Zone Wall Temp & Humidity Sensor | MAMAC Systems

The MAMAC Systems HU-225-2-VDC-17 is a highly accurate and reliable temperature sensor, perfect for industrial applications that demand precise temperature monitoring and control. It features an NTC (negative temperature coefficient) sensor with a resistance of 20k Ohm, providing a wide operating temperature range and excellent sensitivity. The HU-225-2-VDC-17 is constructed with durable materials, ensuring long-lasting performance in harsh industrial environments. Its compact design makes it easy to integrate into various systems. The sensor is designed to operate on a voltage of 2.25 VDC, providing consistent and precise readings. This sensor is ideal for monitoring temperature in machinery, manufacturing processes, HVAC systems, and other industrial applications where precise temperature measurement is critical. Its fast response time and accuracy make it an excellent choice for applications requiring real-time temperature monitoring and control.

• 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.
