Model EDI-54V indicator is an advanced readout unit/logger which can be used to log data from vibrating wire sensors. It can be store calibration coefficients of more than 10,000 vibrating wire sensors so that the value of the measured parameter from the sensors can be shown directly inproper engineering units. For sensors provided with an internal YSI 44005 or equivalent 3 k0hms thermistor, the sensor temperature is displayed directly in degree Centigrade or Fahrenheit.
The indicator has an internal non-volatile memory with sufficient capacity to store about 525,000 readings while scanning from any of the programmed transducer. Each reading in stamped with date and time.
Model EDI-54V indicator uses a smartphone with Android OS as readout with a user friendly software for configuration, retrieving and viewing sensor data.The phone running on Android operating system provides a powerful platform to manage our configuration application efficiently. Since readout unit is a mobile phone, its operation is user friendly and convenient.
The huge computational and image processing power of smartphone allows the application to display the logged data as tables and graphs and keep a record of previous data. This allows the operator to verify the logged data and investigate any anomaly immediately at site. The measured reading can be viewed in terms of time period, frequency, frequency squared or directly in relevant engineering units.
Suitable for input from all two wire vibrating wire transducers with 110 to 150 Ohms (nominal) sensor coil. Thermistor input from sensors provided with integral 3 kOhm (@ 25°C) R-T curve matched YSI 44005 or equivalent thermistor.
Swept frequency excitation, 5 V (typical) peak to peak square wave.
