Globe Temperature Sensor – Modbus
Globe Temperature Sensor, GT-1TM and GT-2TM are used with humidity and ambient air temperature sensors to calculate wet-bulb globe temperature (WBGT).
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 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.
- 6″ copper globe
- Modbus RTU (RS-485) or thermistor output
- Mounts to 1″ pipe
- Durable polyester coating for permanent installation
6 inch (0.15 m) copper globe with polyester coating for long life in outdoor environments.
Power and data are provided through a 4-wire connection. GT-1TM uses an RS-485 (Modbus slave) data connection. Drawing a 3 mA average, GT-1TM is suitable for solar powered instrumentation systems.
GT-2TM is a thermistor device that requires an analog to digital converter to determine temperature.
GT-1TM mounts directly to 1″ pipe using NPT threads or attach a stub to be used with standard 1″ structural pipe fittings.
GT-2TMcan be added as a component of Dyacon MS-100 series weather stations, which can provide WBGT in the heat-stress text message reports.
