HWLP1TX3

BACnet and Modbus communication, 1% RH accuracy, NIST traceable, LCD, temperature transmitter. CE.

HWLP1TX3 $937.51 EA
Quantity:



  • Overview
  • Series Specifications

HWLP Series features embedded BACnet and Modbus communication protocols with humidity and temperature sensing capability. The setpoint slider and pushbutton override offer additional local input. All devices are equipped with a thin-film capacitive sensor that is easily replaceable in the field. The wall-mounted HWLP model features a low-profile housing with an LCD display for easy visibility. All HWLP 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

Calibration-free interchangeable 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
  • Field calibratable
  • Input Voltage 12 to 30VDC, 24VAC; 100mA max.
