![]() ![]() The LED gives an indication that the switch is functioning correctly and gives a visual indication of the state of the relay.Ī fail-safe switch on the circuit board is provided for the user to select either "make" when dry - the normal condition - or "make" when wet, as would be selected for low level duties. The LED will flash approximately once per second when the switch is "off' and will remain constantly lit when the switch is "on". The Series 100 includes a status indicating LED which may be viewed through a lens in the NEMA 4X enclosure cover or with the cover removed, on the explosion proof model. applications - drawing 16.8 MA when "on" and 6.0 MA when "off'. This option is similar to the DIN 19234 (NAMUR) Switching Levels except it is not suitable for I.S. The new option "W" provides a unique step change output for 2-wire 24VDC applications. When relay output is required a SPDT dry contact output version is available with selectable high or low level fail-safe. When specifying the standard 2-wire output version, the switch may also be interfaced directly to a 3 wire 24VDC PLC using a third PLC terminal on the circuit board. The solid state output stage acts as a simple SPST switch, operated by liquid presence. This shift is being monitored continuously and once a present threshold is exceeded, the output changes status.Ī standard two core cable is used to connect the switch in series with the load. As the tuning fork is covered by a liquid or slurry, a corresponding shift occurs in the vibrating frequency of the tuning fork. A piezoelectric crystal system is used to create a 1200 Hz vibration in the tuning fork. The Series 100 has a tuning fork style probe which vibrates at its natural frequency when in air. The Magne-Sonic Series 100 is a two wire device which may be installed in any position in a pipe or vessel to detect the presence of a liquid. It can additionally connect via Bluetooth to the following interfaces: AirLink, SPARKlink Air, and 550 Universal Interface.Series 100 Vibrating Tuning Fork Liquid Level Switch It features an interactive, icon-based user interface within a shock-absorbing case and arrives packaged with SPARKvue, MatchGraph!, and Spectrometry software for interactive data collection and analysis. Designed for use with wired and wireless sensors, the SPARK LXi2 Datalogger simultaneously accommodates up to five wireless sensors and includes two ports for blue PASPORT sensors. See the following guide for details regarding device compatibility: Wireless Bluetooth Product Compatibility »Ĭonsider an all-in-one, touchscreen data collection, graphing, and analysis tool for students. This product can connect directly to your computer or device with the following technologies. ![]() For more information on which is right for your classroom, see our Software Comparison: SPARKvue vs. This product requires PASCO software for data collection and analysis. This new sensor gives you a wireless solution to measure sound level with all the capability of a sound level meter, but adds the flexibility of recording data continuously as a function of time. The dBA scale is commonly used in the workplace to determine the sound level an employee will experience in typical working conditions. Sound level and noise pollution are key measurements in environmental science. The dBA weighting scale filters some of the sound frequencies from a sound source to more closely match the frequency response of the human ear. The dBC weighting scale measures the intensity of sounds in a wide range of frequencies within, and outside the frequency range of human hearing. Sound Level Sensor: The Sound Level Sensor gives you true sound level (intensity) measurements with both dBA and dBC scales. Sound wave measurements work beautifully with the scope and FFT displays in both SPARKvue and Capstone, and the Wireless Sound Sensor is capable of measuring sound wave data wirelessly at sample rates up to 100 kHz. ![]() Students can use this sensor to explore superposition of waves and beat frequencies, while also exploring standing wave harmonics, and the presence of overtones. With graphs of the sound wave measurement versus time, students can explore and analyze wave properties like wave shape, wave speed, amplitude, frequency, wavelength, and much more. Sound Wave Sensor: The Sound Wave Sensor measures relative changes in sound pressure level as sound waves are incident on the sensor. The PS-3227 Wireless Sound Sensor is two sensors in one wireless package: a sound wave sensor capable of measuring relative changes in sound pressure level as a function of time, and a sound level sensor with both dBA and dBC-weighted scales. ![]()
