Barometric pressure sensor VHPS-10-SDI12

membranedigitalimmersed

HyQuest Solutions’ vented hydrostatic pressure sensor VHPS is a programmable submersible level transmitter for measuring water level and temperature in groundwater and surface water. It is low power, robust, and especially designed for use in harsh environments, ensuring longterm measurement stability. The VHPS provides very accurate results: The sensor is vented and automatically self-compensates for barometric pressure changes, i.e. it eliminates errors up to several inches that can be caused by pressure changes. Additionally temperature compensation is calculated from the measured water temperature. Capillary is integrated into the sensor cable with moisture filter at the open end (optional). The fast reacting membrane technology of the VHPS provides long-term measurement stability. Special attention was paid to robustness: The pressure cell is resistant to physical force (3 x burst pressure). The VHPS can be deployed in a variety of environments including natural and grey waters, drinkable water, saltwater and oil polluted waters. You can choose between stainless steel and titanium enclosures, and between three types of cable materials. Equipped with an SDI-12 interface, the VHPS is easily connected to data loggers, and can be configured using standard SDI-12 commands. In addition, SDI-12 is the best choice for low-power applications.
