more information and maximizes system capacity
● Pushbutton override capability from the building control system...local control
in individual rooms to maximize comfort
● Innovative self-calibration algorithm...maximizes performance
● Field calibratable
● Thin-film capacitive sensor element recovers from 100% saturation
● Fully interchangeable element to 1% or 2% accuracy...no calibration
● Calibration-free interchangeable NIST traceable HS element
● HS element is microprocessor profiled with on-board nonvolatile memory
●
Multi-point digital calibration to NIST standards
● NIST certification available
● Replace element in the field...minimizes field calibration downtime
DESCRIPTION
HW Protocol Series 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. These sensors are
calibrated to NIST standards, with certificates available.
The HWLP features embedded BACnet and Modbus communication protocols with
humidity and temperature sensing capability. The setpoint slider and pushbutton
override offer additional local control.
The wall-mounted HWLP model features a low-profile housing with an LCD display
for local indication. All models come with a standard five-year warranty.
