The Alarm-ID™ is a tank overfill and underfill protection system. This PST patented technology provides an alarm point when the identified liquid passes the sensor level either up or down. A series of Alarm-ID™ Units can be installed at key levels on the outside of tanks. The tank contents and even vacancy can be detected and alerts are activated in real-time 24/7. This unique patented technologies greatest advantage is it is non contact, non intrusive installation, means that the sensor can simply, and easily mounted to the outside of tank. The value of this capability is high due to the reduction in installation time and costs vs other technologies which must be in contact (intrusive) with the process liquid or gas.

Principle of Operation: Hawk Measurement Centurion Guided Radar technology sends the radar pulse down a probe to measure liquids & liquid interface (low to high dielectric layers). The pulse hits the surface of the first layer (low dielectric layer) and is reflected back up the probe. The pulse continues to the second interface (high dielectric layer) and is then reflected back to the probe. The transit time for both layers is translated into a distance using time of fight and time expansion.

The Field Electronics 990 Series Communications Converter Simple, compact, versatile, DIN rail mount industrial serial communication converter or line driver.

Our range of signal processing instruments bridge the gap between the traditional passive Data Acquisition I/O devices and the modern complex Programmable Logic Controllers (PLC). Our powerful and versatile devices offer unrivalled performance and many advantages when compared to PLCs. Most notably the ability to perform signal processing ‘out of the box’ – without any programming. Unlike many of the alternatives, our products have truly universal inputs and outputs; featuring support for 30 signal types including most Resistance Temperature (RTD) and Thermocouple (T/C) sensor types. Our inbuilt linearisation algorithm converts the raw output of these types of sensor into temperature units (C/F/K) with a high level of accuracy.
