Schelt Technology

The BTD-300 Thunderstorm Detector is a standalone sensor that reliably detects all forms of lightning out to a range of 83 km. Its unique quasi-electrostatic operating principle provides very high sensitivity with an almost zero false alarm rate and, crucially, the ability to warn of the risk of overhead lightning before the first strike occurs.

HD32MT.1 data logger integrated in an AISI 304 stainless steel outdoor housing. Screen to protect the housing from solar radiation. Powder-coated white.

Double locking, one is a key. Dimensions 450 x 300 x 210 mm. IP66 protection degree.

Supplied with accessories for attachment to the pole diameter 36…52 mm. Provided for 100…240 Vac mains power supply or for power supply from solar panel (version HD32.35FP). Wired and tested.

Optionally, LCD viewer simple (HD32.3D) or with GPS module for automatical time synchronization of the data logger (HD32.D.GPS)

PMsense is a PM1.0, PM2.5 and PM10 Particulate Matter transmitter with RS485 Modbus-RTU output, suitable for outdoor air quality monitoring.

The dust particles concentration is measured using the laser scattering principle.

The transmitter is maintenance-free and has fast response, high sensitivity and an excellent stability.

The PM sensor can be operated in two ways:

• Continuous operating mode: the sensor is always active and measurements are continuously taken. In this mode at least 10,000 hours of PM sensor life are guaranteed.
• Discontinuous operating mode (default): the sensor is activated at regular intervals, when measurements has to be taken. This mode increases the PM sensor life.

On request, an optional CO2 sensor can be integrated in the trasmitter.

The transmitter can be supplied with up to 2 optional configurable 4…20 mA, 0…5 V or 0…10 V analog outputs.
