Silver Gps Enabled Psp Logger

The Data logger model PSP-04 is a micro-controller based data acquisition system, and designed to measure PSP voltage. The unit is having high input impedence and accuracy. This Instrument measures input signal and displays measured data on a Graphic LCD display, directly in engineering units. GPS coordinates of measurement site is also displayed and stored with PSP value.The unit is hand held type confirming to IP67 and has built-in rechargeable batteries. The batteries may be charged with battery charger supplied along with the data logger. Use of latest low power integrated circuits and high speed ADC make the unit ideal for reliable, long term and accurate measurements.

PSP measurement during ON and OFF period is done , after start of respective period with a delay period of 200 m-sec. Highest reading obtained during ON period is memorized as LINE ON PSP and lowest reading obtained during OFF period is memorized as LINE OFF PSP. At cased crossing locations, casing ON and OFF PSP measurements are memorized as casing PSP. Non volatile memory is provided to store data and GPS parameters. Measurement data is stored in non volatile memory, in cyclic manner and remains intact even after removal of batteries.

Window compatible software is provided to down load TLP data to unit and retrieve measurement and TLP data, data to PC through serial port for analysis. The unit is having rugged hand held construction and suitable for field use.
