Overview
Series Specifications

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

Embedded BACnet and Modbus communication protocols (selectable)
Configurable to multiple baud rates
Humidity and temperature sensors in one device at one address...provides more information and maximizes system capacity
Local feature override capability from the building control system
Innovative self-calibration algorithm...maximizes performance
