New extremely accurate recording pressure instruments based on
temperature compensated piezoresistive sensors.

Shows pressure and temperature:
As recorded data - In real time via cable - In real time via satellite.
Accuracy comparable to much more expensive and  more vulnerable oscillating quartz crystal based sensors.
Superior long term stability!

Serial TD- 300 MINI water level recorders will measure and present the ambient water pressure with accuracy +/- 0.01% FS over the entire temperature range from 0-35 degr. C.
Input pressure ranges are from 0- 2 bar to  0- 400 bar. The metering accuracy is comparable with much more expensive and less stable oscillating crystal based level meters.
Temperature accuracy is +/- 1/100 degr. C.

Serial TD 300 is available in two models: Model TD 301 and model TD-302 .

Model TD 301 is a high precision water level / temperature recorder designed for continuous measurement of sea water level and fresh water level in lakes, surface and ground water reservoirs and rivers. The instrument has memory for 22.000  temperature- pressure data sets and is powered from built in type AA lithium cells or from an external  +  6 - +15 V  DC supply . Quiescent current consumption is appr. 50 microampere.
The instrument can be programmed to present and download ASCII formatted pressure and temperature data in physical units from once per second to once per three hours.
Cable lengths up to several hundred meters are possible.
TD 301 is molded in a leak proof polyurethane cast cylinder D= 38 mm L= 170 mm
 

Typical applications for model TD-301
Monitoring of water level in water reservoirs, lakes and rivers
Remote monitoring of ground water level
Tidal measurements
River flow warning

Model TD 302 is basically a model SD-204 MINI STD/CTD without conductivity sensor.
It is recommended for high precision T-D profiles.

NB
Models TD 301, TD 302 and MINI STD/CTD model SD-204  are Plug and Play compatible with Sensordata / SAIV  MINI satellite terminal model SD-400.
By connecting the RS-232 output  from instruments TD- 301, TD 302 or SD-204 to SD-400,
pressure -, temperature - and salinity data from these instruments will be immediately transferred to an ORBCOMM satellite and appear in real time as an email message to the user`s own email address.
