Depth sensors for water level measurements

Technel Engineering offers these PAROSCIENTIFIC Digiquartz Depth Sensors for excellent precision in water level measurements. Typical application accuracy of 0.01% is achieved, even under difficult conditions. Low power consumption, excellent long term stability and high reliability is achieved through the use of a precision quartz crystal resonator whose frequency varies with pressure-induced stress. A quartz crystal temperature signal is provided to thermally compensate the calculated pressure. All depth sensors ranges from 0-30 psia to 10,000 psia and are available with either frequency outputs or integral intelligent electronics with RS-232 and RS-485.
