Description
Globe Temperature Sensor, GT-1TM and GT-2TM are used to estimate the heat stress on the human body. The globe temperature, in conjunction with separate humidity and ambient air temperature measurements, can 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™ uses an RS-485 (Modbus slave) data connection. Drawing a 3 mA average, GT-1 is suitable for solar powered instrumentation systems.
GT-2™ is a thermistor device that requires an analog to digital converter to determine temperature.
Mounting
GT-1™ mounts directly to 1″ pipe using NPT threads or attach a stub to be used with standard 1″ structural pipe fittings.
Accessories
GT-2 can be added as a component of Dyacon MS-100 series weather stations, which can provide WBGT in the heat-stress text message reports.
