Protocol Communication

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-lm capacitive sensor that is easily replaceable in the eld. These sensors are
calibrated to NIST standards, with certicates available.

The HWLP features embedded BACnet and Modbus communication protocols with
humidity and temperature sensing capability. The setpoint slider and pushbutton
override oer additional local control.

The wall-mounted HWLP model features a low-prole housing with an LCD display
for local indication. All models come with a standard ve-year warranty.

APPLICATIONS

● Oce buildings, schools, or other systems utilizing BACnet or Modbus protocol

HUMIDITY

FEATURES

● Embedded BACnet and Modbus communication protocols...compatible with

many existing control systems

● Congurable to multiple baud rates

● Humidity and temperature sensors in one device at one address...provides

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-lm 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 proled with on-board nonvolatile memory

● Multi-point digital calibration to NIST standards

● NIST certication available

● Replace element in the eld...minimizes eld calibration downtime
