Product Highlights

The SWE73T is a cost-effective and compact digital panel indicator designed for versatility. It supports Pt 100/Pt 500/Pt 1000 type input and automatically detects two, three, or four wire sensors. With a measurement range spanning from -100°C to +600°C, the input is fully linearised, ensuring accurate readings. The 4-digit LED display effectively presents the results. These indicators utilise 16-bit A/D converters, ensuring exceptional stability and precise measurements. Thanks to the RS-485 interface, setting up measurement networks in production process monitoring systems is effortless. Moreover, the indicators can function as intelligent, programmable digital converters for input signals in computer systems. Configuration of the meter can be conveniently accomplished using an IR remote controller or the free S-Config software via the RS-485 communication port. Additionally, the device can be customised according to specific customer requirements, making it highly adaptable.
