VERIS HWX2NSTM
Veris | HWX2NSTM | RH Wall | 2% | NIST | Temp | 20k NTC
Veris
2% accuracy, No LCD, 20k ohm NTC thermistor. HWL Deluxe humidity transmitters provide an ideal solution for measuring relative humidity in all conditions. All devices are equipped with a thin-film capacitive sensor that is easily replaceable in the field. The wall-mounted HW model features a low-profile housing with an LCD display for easy visibility. All Deluxe models come with an extended five-year warranty. APPLICATIONS Managing energy systems Controlling HVAC systems for improved comfort and energy savings Museums, schools, printing shops, and other locations requiring humidity control Facilitating compliance with ASHRAE standards for environmental control and indoor air quality Sense humidity in harsh environments Thin-film polymer capacitive sensor element recovers from 100% saturation Replace element in the field...maintain accuracy and minimize downtime Easy Installation Polarity insensitive analog output...flexible systems compatibity...save time in the field, and stock fewer devices Calibration-free interchangeable NIST traceable HS element HS element is microprocessor profiled with on-board nonvolatile memory Minimizes field calibration downtime HS Element Digitally profiled thin-film capacitive (32 bit mathematics) U.S. Patent 5,844,138 Accuracy at 25°C from 10-80% ±1% at 12-60% RH (Multi-point calibration, NIST traceable) Reset Rate** 24 hours Stability ±1% @ 20°C (68°F) annually, for two years Operating Humidity Range 0 to 100% RH (non-condensing) Hysteresis 1.5% typical Linearity Included in accuracy spec. Temperature Coefficient ±0.1% RH/°C above or below 25°C (typical) Analog Output 4-20mA mode: 2-wire, polarity insensitive, (clipped and capped); 0-5V/0-10V mode: 3-wire, observe polarity Scaling 0-100% RH Operating Temperature Range 10° to 35°C (50° to 95°F) Input Power*** 4-20mA mode: loop powered 12-30VDC only, 30mA max.; 0-5V/0-10V mode: 12-30VDC/24VAC, 15mA max. Temperature Transmitter Output Digital, 4-20mA, (clipped and capped) or 0-5V/0-10V output; accuracy ±0.5°C (±1°F) typical *Specified accuracy with 24VDC supplied power with rising humidity. RTD/Thermistors are not compensated for internal heating of product.**Reset Rate is the time required to recover to 50% RH after exposure to 90% RH for 24 hours.***One side of transformer secondary is connected to signal common, so an Isolation transformer or dedicated power supply may be required.Shielded cabling is required for conformance to EMC standards.
