Recording Device Combines Digital Pressure Gauge With Data Logger

The LEO Record by Keller combines a high-accuracy digital pressure gauge with an autonomous data logger. The result is an instrument that simplifies the process of tank and pipe pressure monitoring and leak testing.

The digital pressure gauge combines a piezoresistive silicon pressure sensor with microprocessor-based signal conditioning to achieve an accuracy of 0.1% full scale total error band. The LEO Record is available in pressure ranges up to 30,000 psi and can be built with different pressure connections to ensure compatibility with new or existing installations.

The integral data logger measures and records pressure and temperature readings at user-defined intervals up to 1 measurement per second. The instrument will record up to 57,000 data points and store them in secure solid-state memory until they are retrieved via connection to a PC running Keller’s Logger 5 software.

The Keller software is compatible with Windows operating systems and can be used to configure test parameters, frequency and units of measure, along with battery capacity and data download. Downloaded test results can be displayed in both graphical and tabular format for simplified viewing and reporting.
