Panel voltmeter with E-Ink display

31 January 2018 Test & Measurement

The PanelPilot SGD 21-B from Lascar Electronics, a leading maker of display panels for industrial applications, is a low-cost and ultra-low-power single-channel voltmeter with a sleek monochrome E-Ink display.

E-Ink displays are typically used in a range of electronic consumer devices – most notably in a leading e-book reader product – but are now starting to see use in industrial applications. These types of displays have two major advantages over alternative technologies: firstly, they are readable even in extreme sunlight; and secondly, they offer very low power consumption.

The PanelPilot SGD 21-B comes with a 2,1” dot-matrix display with a 250 x 122 pixel resolution. The product takes advantage of the PanelPilot B Windows-based platform, which allows users to configure and customise a range of Lascar compatible displays with the click of a mouse. The use of pre-loaded display layout templates, which are configurable for further customisation, enables users to get up and running very quickly, without writing any code.

For the new PanelPilot SGD 21-B, the software platform enables users to choose from a selection of analog and digital voltmeter apps, and then customise labels, scaling and alarms for their own specific application. The device allows the setting of two alarm levels with a dedicated alarm output and a configurable digital I/O pin. A splashscreen can be added to display on power-up. Once the app is complete, it can be uploaded to the SGD 21-B display using a USB cable.

Key to the product is its 4 to 9 V d.c. power supply and its very low power consumption, which means it can be used in mobile applications that are powered by batteries. The display measures 73,8 x 37,5 x 10,8 mm and has an operating temperature range of 0°C to +40°C.
