Saiv - Model TD301/TD303 -Depth & Temperature Recorder
The TD301/TD303 are precision instruments measuring temperature and depth (pressure) in the sea, lakes, water reservoirs, groundwater, rivers and on R.O.V/A.U.V. etc. All settings like measuring interval, real time clock etc, are accessed via menu. The programmed settings and calibration coefficients are maintained in nonvolatile eeprom, and will not be changed/lost if power is disconnected. The model TD301 has a built-in replaceable battery for self- contained recording applications. On/Off- switching is by a magnetic key or from keyboard.
The model TD303 is for on-line applications with external power supply and has an extra feature of 5Hz sampling with programable output formats to suit the host unit. Both units have a built-in data memory "ring memory" where the oldest data will be overwritten when memory is full. Data are recorded in physical units and simultaneously transmitted via an RS232 I/O watertight connector for on-line use. Robustness and complete protection from leakage has been obtained by vacuum molding the electronic and all other components in solid polyurethane. A comprehensive PC-program is supplied with the units for easy communication, programming and presentation/processing of data. For remote readout and monitoring, the manufacturer offers several options: Communication Unit CU901, for two-way communication via Iridium satellite, GPRS with embedded web server, GSM and UHF/VHF.
