Description
The Simex SWE-N55L is a compact, ultra-efficient loop-powered digital indicator designed for local process visualisation without the need for an external power supply. By drawing its operating power directly from the 4-20 mA current loop, it simplifies field installations in remote or hard-to-reach locations. Housed in a durable IP65 wall-mount case, it features a clear 4-digit (13mm) red LED display capable of displaying values from -999 to 9999. The device is highly adaptable, supporting linear, square root, and user-defined characteristic curves (up to 20 points), making it ideal for flow, level, and pressure monitoring. With an optional bi-stable relay for basic signalling and full programmability via an infrared remote, the SWE-N55L offers a professional-grade monitoring solution in a small, 64 x 58 mm footprint.
