SWE-73-L Loop Powered Process Meter

SWE-73-L Low Cost loop Powered Meter

The SWE-73-L Process Meter from Simex is engineered for straightforward, reliable process measurement in a compact form factor. This low-cost digital indicator is powered directly from the 4-20 mA current loop, eliminating the need for an external power supply and simplifying installation. The device features robust input protection circuits to safeguard internal electronics against overload, ensuring long-term durability and dependable operation in demanding environments.

The SWE-73-L offers flexible signal processing, allowing users to select from predefined transfer functions such as linear, square, and square root, or to define a custom characteristic with up to 20 points. The measured value is displayed on a bright, four-digit red LED display, with a configurable decimal point for clear and precise readout. Optional features include an SPDT relay output for alarm signalling and an IP65 front frame for enhanced protection. All parameters can be easily programmed using the IR remote controller, making setup and adjustments quick and user-friendly.
