GALLTEC FG120 / TFG120 Humidity and Temperature Sensors

Humidity and Temperature Sensors for Indoor Environmental Monitoring

The GALLTEC + MELA FG120 and TFG120 Sensors provide relative humidity and temperature measurement options using robust Polyga® humidity sensing technology for indoor monitoring applications.

Part of the Universal Polyga® Transmitters range, the FG120 and TFG120 are designed for indoor environmental measurement. The FG120 is identified as a relative humidity sensor, while the TFG120 combines humidity and temperature measurement. Both belong to a product family known for its measuring performance, durability and accuracy under high-humidity conditions.

Polyga® Humidity Measurement Technology

The FG120 and TFG120 incorporate the Polyga® humidity measuring element, which is designed for durable and reliable measurement, including applications involving extended periods of high humidity.

The original product information highlights the measuring element's high-humidity accuracy, robust construction and ability to be adjusted and cleaned in water. These servicing characteristics refer to the measuring technology and should not be interpreted as water resistance of the complete IP20 instrument housing.

Humidity and Temperature Measurement

The product range provides relative humidity measurement from 0 to 100% RH, with a specified humidity accuracy of ±2.5% RH above 40% RH. The published temperature range is -10°C to +60°C, with temperature accuracy specified as ±0.5 K.

The FG120 is intended for relative humidity measurement, while the TFG120 provides an option where humidity and temperature information are both required.

Available Signal Output Versions

The series includes different signal output arrangements for compatible measurement and monitoring systems.

• (T)FG120H: Version with resistance output.
• (T)FG120: Version with current or voltage output.

The original product information lists several linear resistance output ranges. The appropriate model and output version should be selected according to the receiving instrument and measurement requirements.
