The Only True Self Testing Probe
The MCG 1090 Level Alarm Probe brings state of the art technology to overfill protection. The competitors systems typically only check the wiring and probe electronics. The MCG 1090 includes a solenoid to physically move the displacer as an actual level would. In keeping with the L&J tradition, the MCG 1090 has gone a step further than the competition in providing high reliability and low maintenance. The MCG 1090 offers the most reliable protection available against dangerous and costly overfills.
Typically, a high level alarm probe is mounted in a poor environment and sits inactive for years at a time. This makes regularly scheduled testing the most important factor in reliability. The optional remote self-testing feature of the MCG 1090 makes regular testing of the probe easy and convenient. The probe can be wired to be tested from tank side or the control room. If coupled with the L&J MCG 7000 Alarm System, all probes can be automatically tested at pre-programmed intervals, complete with a printout of probe conditions.
Two wiring configurations are available with the MCG 1090 Probe. Where independent wiring is required, individual wiring from each probe may be run directly to the control room or alarm panel. If independent wiring is not required, a standard 4-wire data highway can be used to multiplex up to 128 probes to the MCG 7000 Alarm System.
Remote Data Acquisition
For a complete alarm system the MCG 1090 probe can be coupled to the MCG 7000 Alarm System. The MCG 7000 provides automatic self-checking, printouts, and discrete outputs for horns, emergency shut-off, as well as an optional communications port. The MCG 1090 can be configured with the standard L&J 4-Wire Data Highway port to provide remote alarm data acquisition for your gauging system along existing wiring.
