HW Series Wall Humidity Sensor

HW series wall humidity sensors are equipped with a thin-film capacitive sensor that is easily replaceable in the field. Wall humidity sensors are calibrated to NIST standards with certificates available. The wall-mounted HW model features a low-profile housing. It is required for Controlling HVAC systems for improved comfort and energy saving.

• Sensor element - thin-film capacitive sensor element recovers from 100% saturation
• Interchangeable element - fully interchangeable element to 1% accuracy no calibration
• Flexibility - polarity insensitive, 2-wire 4 to 20 mA or 3-wire 0 to 5/0 to 10 V DC versions flexible systems compatibility save time in the field, stock fewer devices
• Field replaceable - replace element in the field maintain accuracy and minimize downtime
• On-board memory - HS element is microprocessor profiled with on-board non volatile memory
• Calibration-free interchangeable NIST traceable HS element
• 1% NIST
