Brooks® LR-056

Brooks® LR-056 Transducer Display
Accurate, miniature displays for point-of-use pressure monitoring
Description
Local display of process pressure improves safety and
quality control of gas delivery systems. The LR-056 allows a
4-20 mA sensor to digitally display its pressure and send its
signal to a final destination. The sensor, such as the Brooks®
SolidSense II® pressure transducer, connects to the back of
the LR-056 with a 4-pin Bendix® connector. The LR-056
connects to the loop through a 2-wire pigtail cable. The LR056 offers a real time reading. This device is loop powered
and single channeled. The LR-056 has two user
programmable setpoints which define a window - if the
window is entered or left an output signal is generated.
