Dyacon Globe Temperature Sensor for WBGT Measurements
Globe Temperature Sensor, Mounted

Globe Temperature Sensor – Modbus

Globe Temperature Sensor, GT-1TM is used with humidity and ambient air temperature sensors to calculate wet-bulb globe temperature (WBGT).

PN: GT-1.



Product Details




Globe Temperature Sensor, GT-1TM is used to estimate the heat stress on the human body. The globe temperature, in conjunction with humidity and ambient air temperature measurements is used to calculate the wet-bulb globe temperature (WBGT).

GT-1 is a full-size, 6″ diameter globe intended for permanent installations. The sensor conveniently mounts over 3/4″ pipe or onto 1″ pipe using standard structural pipe fittings.

Available either with a Modbus output or 10 kohm thermistor, GT-1 is compatible with a wide range of instruments, including Dyacon weather stations.

Feature Summary

  • 6″ copper globe
  • Modbus RTU (RS-485) (thermistor output available)
  • Mounts to 1″ pipe
  • Durable polyester coating for permanent installation

Manuals & Software



Key Features

6 inch (0.15 m) copper globe with polyester coating for long life in outdoor environments.

Data Connection
Power and data are provided through a 4-wire connection. GT-1 uses an RS-485 (Modbus slave) data connection. Drawing a 3 mA average, GT-1TM is suitable for solar powered instrumentation systems.

GT-1TM mounts directly to 1″ pipe using NPT threads or attach a stub to be used with standard 1″ structural pipe fittings.

GT-1TM is a component of Dyacon Heat Stress monitor, HSM-1TM, which provides a wireless system for remote heat stress monitoring, logging, and safety alerts.
