Pressure Measurement & Control


Analysing pressure peaks

November 2018 Pressure Measurement & Control

Keller’s Leo 5 high-resolution digital manometer features precise sensor technology, fast signal processing, peak recording and data storage with a time stamp. Designed for deployment in hostile environments, the instrument features a robust stainless steel housing, safety glass front, a 16 mm backlit display and capacitive touch controls.

Recording and analysing pressure peaks

Undetected pressure ‘spikes’ are a common cause of premature wear and untimely failures in pneumatic and hydraulic systems. In freshwater systems, this phenomenon is sometimes called ‘water hammer’. The Leo 5, with its pressure peak analysis mode, will sample and record system pressure at a rate of 5 kHz and with 16 bit resolution, enabling the troubleshooter to positively characterise system behaviour. With storage capacity for over 50 000 peak values, including temperature and time stamp, data from the data is exportable for detailed analysis via the included USB interface.

In the standard measurement mode, the unit operates at a sampling rate of 2 kHz and with an A-to-D resolution of 20 bits. The line-up includes seven standard full-scale pressure ranges between 3 and 1000 bar. In the temperature range of 0-50°C, the TEB (total error band) for pressure is ±0,5% FS.

Other features

The LEO 5 is available with a wide range of optional features, including a standard radio interface for measurements in inaccessible or mobile locations. Traditional analog outputs of 4-20 mA and 0-10 V DC and up to two switch outputs for process control and monitoring can also be provided. Configuration and data transmission take place via USB or RS-485 interface. Special housing materials, pressure connections and other user-specific options are available.

With high resolution for accurate measurement, pressure peak analysis and measurement data recording, the instrument has been adopted as an indispensable tool by pneumatic and hydraulic system mechanics.
