Chapter 2 - Product Overview
The T6050 SurgeGard™ is an incipient surge-conditioning module designed to continuously monitor
the frequency flow, pressure or current oscillations occurring before the compressor reaches the
actual surge point(s). SurgeGard™ is patented and has been successfully used in many compressor
control systems.
The T6050 continuous analog peak-detector circuit is more efficient (less than 1 ms) and reliable
than the digital sampling (2-10 ms sample rate) for both incipient surge control and for surge spike
detection. In both applications (analog or digital), high speed transmitters should be used when
implementing incipient surge detection techniques.
The T6050 is loop powered and consists of a differential input band pass (1Hz to 10Hz)
amplifier/filter, a low pass filter (10Hz), absolute-value, peak detector and a voltage-to-current
converter; all enclosed in a termination type electronic component housing.
The T6050's small size and built-in termination assembly allow the module to be mounted virtually
anywhere on 32 or 35mm width standard DIN/EN rail.
