The Anderson-Negele SR458B157B21A1N is a sanitary electronic pressure transmitter in the SR series, designed for cleanable process environments in the food and beverage, pharmaceutical, and life sciences industries. It measures pressure from 0 to 1379 bar and operates on a 30 VDC supply, delivering a 4-20 mA output proportional to the measured pressure, with an optional built-in LCD display available in SR-series configurations. This exact model—SR458B157B21A1N—appears in distributor catalogs as discontinued, which may affect availability, though the device's role remains a standard sanitary transmitter in its family. The transmitter is intended to provide reliable, continuous pressure monitoring to process controllers and instrumentation, making it suitable for applications requiring sanitary construction and precise pressure readings.
