Digital manometer for analysing pressure peaks

3rd Quarter 2015 Hydraulic systems & components

Keller has introduced the first of a new generation of high resolution digital manometers. The LEO 5 features precise sensor technology, fast, high resolution signal processing, peak recording and data storage with a time stamp. Designed for deployment in hostile environments, the LEO 5 features a robust, stainless steel housing, safety glass front, a 16 mm backlit display and capacitive touch controls.

Undetected pressure spikes are one of the common causes of premature wear and untimely failures in pneumatic and hydraulic systems. The LEO 5, with its pres­sure peak analysis mode, can 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 LEO 5 is exportable for detailed analysis via the USB interface.

In the standard measurement mode, the LEO 5 operates at a sampling rate of 2 kHz and with an A-to-D resolution of 20 bits. The LEO 5 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. When temperature conditions are stable, the LEO 5 is capable of achieving a TEB accuracy of ±0.01% FS.

With high resolution for accurate measurement, pressure peak analysis and measurement data recording, the LEO 5 is quickly adopted as an indispensable tool by the pneumatic or hydraulic system mechanic.
