mACS: Pronounced "Max"          Go to mACS >
Contegra's milli-Amp Current Simulator (i.e. Max) is a two-wire loop-powered device that is often used during system test and setup.  The mACS acts like an adjustable level transmitter.  Using the mACS the installing technician can test and calibrate a control system without the need for a pressure cal stand or water in which to submerge a sensor.

ISB-M1d: Intrinsically Safe Barrier          Go to ISB-M1d >
Intrinsically safe installations require both a third-party-approved sensor/transducer and intrinsically-safe barrier.  Contegra's SLX 130-MIS submersible transducers are UL approved for installation in hazardous locations.  The ISB-M1d is a UL approved barrier that operates in conjunction with the SLX 130-MIS.

Surge32: Surge Suppressor (Non-IS)          Go to Surge-32 >
Contegra's Surge32 is a surge suppressor that's typically applied at each end of a 4-20mA transmission line.  Electrical surges (e.g. lightning) can wreak havoc with control equipment and level transmitters.  Typically elevated lines are more [prone to damage than buried lines.  Therefore, a surge suppressor is often applied to the transmission line when the line enters the control panel.  Further, another surge suppressor is applied at the remote/sensing location to protect the level sensor.

Surge-KG1: Surge Suppressor (IS)          Go to Surge-KG1 >
Contegra's Surge-KG1 is an intrinsically-safe, third-party-approved surge suppressor which, when properly installed/wired, may be located in a hazardous area.     The Surge-KG1 surge suppressor is typically applied at the remote end of a 4-20mA transmission line near the level sensing transducer.  Electrical surges (e.g. lightning) can wreak havoc with control equipment and level transmitters.  Typically elevated lines are more [prone to damage than buried lines.  Therefore, a surge suppressor is often applied to the transmission line when the line enters the control panel.  Further, another surge suppressor, such as the Surge-KG1 is applied at the remote/sensing location to protect the level sensor.

T423: Voltage-to-Current Converter          Go to T423 >
Contegra's T423 is a two-wire loop powered device.  The T423 provides a stable 5VDC (nominal) excitation voltage to Contegra's SLX 130-E submersible transducers.  Further, the T423 converts the transducer's 0.5-4.5 VDC (nominal) signal into a calibrated 4-20 mADC output.  The T423 provides zero and offset adjustments.  Additionally, the T423 contains on-board  signal simulation which allows the field service technician to calibrate the T423 without the need to fill the tank with liquid.  

T425: Voltage-to-Current Converter          Go to T425 >
Contegra's T423 is a two-wire loop powered device.  The T425 provides a stable 5VDC (nominal) excitation voltage to Contegra's SLX 130-E submersible transducers.  Further, the T425 converts the transducer's 0.5-4.5 VDC (nominal) signal into a calibrated 4-20 mADC output.  The T425 provides zero and offset adjustments.
