Sealed Gauge (SG) is a type of reference pressure measured relative to a fixed approximation of atmospheric pressure by sealing ambient air pressure on the reference side of a pressure sensing device during manufacture.
A preferred method of creating a sealed gauge reference is to seal a high vacuum on the reference side and subtract a 1 bar pressure offset from the measurement output.
Also see gauge reference pressure.

Event triggered high sampling rate pressure logger - This pressure logger can record for months at time at a slow logging rate, and when a predefined event threshold is exceeded it will record pressure at a much faster rate.
Sonde OEM water depth sensor for 300m deep borehole - We are looking to integrate a pressure sensor into the bottom of a Sonde. The sensor will be used to monitor the water depth in a borehole up to a maximum of 300m.
