Weschler Instruments offers product customizations to meet special user requirements. The Weschler application and design teams will work with customers to define and deliver an optimized solution. A changes can be as simple as a minor modification of an existing product or as complex as a major redesign of a product platform. Some examples of customizations for analog & digital products:
Illuminated MPH Meter with Speed Limit Indicators
This custom speedometer was requested by a metro transit system for use in their light rail cars. A standard switchboard meter was modified to incorporate backlight circuitry, a translucent dial and nine LED indicators. The appropriate LED is activated by an external signal.
Transformer Temperature Monitor
A major electric utility requested an upgrade of the analog temperature indicator used on oil-filled transformers since the 1940s. Weschler modified and repackaged circuitry from its digital bargraph line to provide a unit with both analog and digital displays. The gas bulb bourdon tube sensor was replaced with a stable platinum RTD. The unit also included relay outputs and SCADA interface.
A subcontractor providing equipment for a nuclear power plant contacted Weschler to design & manufacture the required process displays for their loop controllers. Utilizing elements of its digital bargraph technology, Weschler provided a three bar indicator with alpha-numeric readout and sealed membrane switches. In addition to the display for SV, PV & MV, the Manual/Auto Station allowed operators to input process value changes.
An equipment supplier to oil & gas drillers required a large readout of load cell output, to use on drilling platforms. Weschler’s BG-261 8″ Digital Bargraph Meter was internally modified to withstand the rig’s high shock & vibration. A special extended operating temperature range, down to -35°C, met the need for all season operation. The spray-tight front bezel assured weather protection even with an open enclosure door.
