UPS-HSR USB Pressure Sensor with High Sample Rate Logging
USB ready digital pressure sensor for recording pressures with a high speed sample rate of up to 1 kHz to a computer.
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.
Water system peak demand pressure and flow data logger
I have a small water system and I would like to monitor and record the pressure in psi and the flow in gpm in the system over an extended period of several months in order to determine the times and duration of peak demand and low pressure.

Logger for verifying water supply pressure over 7 days
The P-Triton-P is specifically designed for monitoring water supply pressures and storing readings for long term tests.
SG – Sealed Gauge
Sealed Gauge (SG) is a type of reference pressure measured relative to a fixed pressure of approximately 1 bar absolute.
Gauge Reference Pressure
Gauge reference pressure is a pressure measured relative to atmospheric or barometric pressure. The most used pressure reference is gauge pressure which is signified by a (g) after the pressure unit (e.g. 30 psi g), and means that the pressure measured is the total pressure minus atmospheric pressure. There are two types of gauge reference […]
Using Sealed Gauge Reference Pressure Sensing Devices
Sealed gauge or SG is a type of pressure reference typically used when a vented reference is not possible because of the type of sensing technology or the need to provide secondary containment overpressure protection.
What is the difference between sealed gauge and vented gauge reference?
Gauge reference pressure measuring devices read pressure relative to atmospheric pressure. This ensures that the pressure reading is nominally zero when the pressure on the device is released.

Submersible sensor for measuring sludge pressure in pipe
Submersible pressure sensor to measure 10 bar pressure in pipe that is IP68 for long term submersion in sludge up to 6 metres deep.
Difference between vented and non-vented water level measurement
A hydrostatic level probe typically uses pressure sensor to measure the water level. The main component of a pressure sensor is the sensing diaphragm which converts the difference in pressure between either side of the diaphragm into a measured signal. The front of the diaphragm measures the water level pressure (hydrostatic pressure) plus the barometric […]
What does the suffix a, abs, d, dp and diff, g, rel and sg mean after the pressure units in a pressure range?
There is a loose convention across manufacturers for designating the type of reference that a pressure sensing device has, which can be confusing if you are unfamiliar with specifying this often overlooked but critical specification parameter.
What is the difference between gauge and absolute pressure measurement
Determining whether you need gauge or absolute reference pressure is a very important to selecting the right pressure range for a pressure instrumentation.
