Felix Technology Inc. products

The SMART2000 Telemetry System is a Hi-Tec acquisition, logging, and control system based on ARM microprocessor. Due to its design architecture, it can serve all the environmental applications including meteorology, hydrology, and water and air quality. The Felix Technology RTU has 8 isolated differential analogue inputs, enabling data acquisition with a high resolution up to 16 bits. It features 6 digital inputs/outputs, all protected allowing the user to control various sensors and auxiliary equipment.

The SL300 ultrasonic snow depth sensor provides a total system in a compact package, containing an ultra sensitive electrostatic transducer and the supporting circuitry to provide a 0 to +5 or 0 to +2.5 VDC output with fully independent zero and span adjustments over the entire operating range of detection from 1.5’ - 20’. The piezoelectric crystal inside the transducer converts electrical pulses into sound energy that travels in the form of a wave at the established frequency and at a constant speed in a given medium.

The accurate measurement of rain and snow precipitation remains one of the most basic elements of hydrological and meteorology studies. The FT7360 Precipitation Gauge has been designed to measure rainfall and precipitation in remote and unattended locations. The FT7360 is a high quality instrument that provides accurate measurements with long term performance. The tipping bucket design allows accurate repeatable measurements, requires no regular operator maintenance, and is economical and proven in operation. All components of the FT7360 reflect the environmental requirements of a continuous duty instrument.

Felix Barometric Pressure Sensors FT5006 series have very fast response with excellent accuracy, repeatability and long term stability over a wide range of pressure and temperature. The FT5006 features robust and low maintenance construction that will withstand a wide range of adverse weather conditions, and consistently collects reliable barometric pressure data for environmental monitoring applications.

The Pressure sensors FT5005 series are used to determine the absolute atmospheric pressure. The optional output analog signal can be used for meteorological purposes or as input signal for control and regulation applications. With a piezoresistive pressure sensor and signal conditioning electronic the actual air pressure will be transformed into a proportional standardised electrical output and is displayed with a resolution of 0.1 hPa. Main features are; switchboard housing, low weight and low power consumption.

Visibility sensor is configured for accurate measurement of visibility in the densest of fogs to very clear air conditions and is the refinement of 2 decades of experience and technology resulting in a compact, robust instrument with excellent performance.

The Aspirator Psychrometer FT3060 series are used for measuring the air temperature and the humidity. Two parallel mounted, equal mercury thermometers are used. The bulb of one thermometer (wet bulb thermometer) is covered by a wick, which must be moistened for a measurement.

The temperature sensor type FT2019 comprises an encased hard glass platinum resistance Pt100 according to DIN 60751 B, 1/3 tolerance, that is placed on a plastic shaft and is mounted by means of a screwed joint to the side wall of an aluminum cable box.

The hygrometer FT3122 is used to measure the relative humidity by means of a special prepared hairstring element, with direct indication of relative humidity and electrical transmission. The temperature range is from -60 to +70°C and the humidity range is from 5% to 100%. Measuring the relative humidity is based on the fact that the dimensions of hygroscopic materials will change with the ambient humidity. Selected and pre-treated human hair as well as “PERNIX”-elements, which are manufactured by a special process, are such hygroscopic materials. They are particularly suited for measuring purposes, because their longitudinal expansion and contraction are very large, and the measured values are consistent. Furthermore the changes will be independent of the change in temperature. The sensor contains a number of `PERNIC`-elements, combined in bundles and framed in three sections in order to increase the displacement force.

Humidity/Temperature FT3030 series Sensors are used for the measurement of the relative humidity and the air temperature simultaneously. A capacitive measuring element is used for the measurement of the relative humidity and a PT100 is used for the measurement of the air temperature. Both sensors are located in a measuring probe, protected by a membrane filter. The measuring probe is placed inside a solar radiation shield made of a defined white colored plastic. There is also an electrically ventilated version available for measurement of the exact temperature when wind or drift are absent.
