Multichannel Sensor Unit wirelessly transmits data.
Press Release Summary:
Suited for extended data acquisition and recording applications, MITE WIS can be configured for up to 4 channels of voltage or resistive sensors. Autonomous device transmits data to RF Receiver, which is connected to PC via RS-232 or USB connection. Offering 3 modes of data transfer, unit offers programmable sample rates from one sample/15 sec to 1 sample/hr. Each transmission is passed to PC where GUI decodes, time-stamps, saves, and plots incoming data.
Original Press Release:
The MITE WIS Multichannel RF Wireless Sensor Unit
Invocon, Inc. is pleased to introduce MITE WIS, a small, extremely low-power, autonomous, wireless device designed for extended data acquisition and recording applications. Each unit can be configured for up to four channels of voltage or resistive sensors: strain gages, resistive thermal devices (RTDs), pressure sensors, humidity sensors, accelerometers, etc.
Data is transmitted wirelessly to an RF (radio frequency) Receiver, which is connected to a PC via the RS-232 or USB connection. Any number of MITE WIS units can be placed within a single RF coverage area. There are three modes of data transfer from the MITE WIS units to the Receiver: (1) data is transmitted via RF in real-time and graphically displayed and stored in the PC as an ASCII file; (2) data is stored into non-volatile memory and later downloaded via RF to the Receiver; or (3) a combination of modes 1 and 2, transmitting data in real-time while storing the data locally.
Each data transmission from the MITE WIS is passed to the PC where the Graphical User Interface (GUI) decodes, time-stamps, saves, and plots the incoming data in real-time. Sample rates are programmable with the GUI from 1 sample per 15 seconds to 1 sample per hour. The GUI incorporates unique temperature-compensated calibration coefficients for each MITE WIS channel allowing for accurate, simultaneous conversion to engineering units for any type of sensor.
The MITE WIS unit was designed as an extended-life unit. The battery has a life of two years under typical operating conditions and with most transducers. The battery is commonly available and easily replaced by removing the threaded cap. The electronics are entirely encapsulated, the battery is sealed with a gasket, and all connectors are intended for rugged outdoor usage.
