Globe Temperature Sensor – Modbus

Description

Key Features

Manuals & Software

Globe Temperature Sensor, GT-1^TM and GT-2^TM are 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 and -2 are full-size, 6″ diameter globes intended for permanent installations. The sensors conveniently using standard structural or plumbing pipe fittings.

Available either with Modbus output (GT-1) or 10 kohm thermistor (GT-2), the sensors are compatible with a wide range of instruments, including Dyacon weather stations.

Feature Summary

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

Key Features

Construction
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^TM uses an RS-485 (Modbus slave) data connection. Drawing a 3 mA average, GT-1^TM is suitable for solar powered instrumentation systems.

GT-2^TM is a thermistor device that requires an analog to digital converter to determine temperature.

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

Accessories
GT-2^TMcan be added as a component of Dyacon MS-100 series weather stations, which can provide WBGT in the heat-stress text message reports.
