Weather Measuring Instruments
Rainfall Measuring Instrument: Rain Gauge and Transmitter
The Comptus Rain Gauge is used in many industrial applications including rainwater and irrigation control. The tipping bucket gauge is easily integrated with controls that can count switch closures to determine and record amount of rainfall.
The design simplicity of the Comptus Rain Gauge rainfall measuring instrument provides trouble-free operation and accurate rainfall measurement. Our weather instruments, rain gauge and transmitters meet the US Weather Service specifications and have high-quality 304 stainless steel to ensure long life.
The Comptus Rain Gauge is factory calibrated to produce a switch closure for every 0.01” of collected rainfall. Consult the sales team at Comptus should other calibration setups be desired.
Air Temperature and Humidity Sensors
The Comptus A70-HT humidity and temperature sensor provides analog output signals proportional to relative humidity and temperature. These units are used in conjunction with electronic data collection systems or for input to control systems. They are readily combined with meter relays to provide custom controls. Systems come with outputs of 0-1 V or 4-20 mA. The A70-HT humidity and temperature sensor is powered from 6-30 VDC.
Relative humidity is detected by a thin-film polymer capacitor humidity measurement sensor with excellent durability in harsh environments. The temperature and relative humidity sensor has a hydrophilic membrane under a wire mesh screen.
Many types of industries use this humidity measurement sensor to control and maintain proper humidity levels. This sensor is designed with robust capabilities, allowing it to provide stable and accurate results.
The Comptus A70-HT is manufactured in the USA.
Barometric Pressure Transmitter
Comptus Barometric pressure sensors utilize an integrated silicon, absolute pressure sensor with internal temperature compensation. The sensor is mounted to the signal conditioner board. A 3/16 inch diameter tube may be attached to the sensor to provide remote pressure sensing. The output of the sensor is scaled to provide the desired output signal.
Comptus Barometric Pressure sensors are available with outputs of 0-‐1 mA, 0-‐1V or 4-‐20 mA. All sensor systems may be powered from either 120 VAC, 230 VAC or 12-‐24 VDC.
Comptus Barometric Pressure sensor instruments are available in a variety of packages including steel JIC boxes meeting NEMA 12 standards, weatherproof fiberglass enclosures meeting NEMA 4X, IP66 and IEC 529 standards and track mounted versions. NEMA 12 enclosures provide protection from dust for indoor applications. NEMA 4X enclosures may be used indoors or outdoors and provide protection from corrosion, wind blown dust and rain and ice. Track mounted versions are intended for mounting inside an enclosure provided by the user. Where required, electrical connection to the sensor is via terminal block. A barrier strip is provided for connection to operating power.
Each Comptus barometric pressure sensor is provided with a detailed instruction manual. Comptus barometric pressure sensors are manufactured in the USA.
