Specifications and Features
8450 Pressure Transmitter
The Signet 8450 Pressure Transmitter is a unique instrument that offers local or remote display with current and relay outputs. This model offers exceptional repeatability and accuracy over a wide operating pressure range. The instrument is available in field and panel mount configurations, dual channel input and is equipped with two 4 to 20 mA outputs, fully scalable and reversible for each input channel. Configurations include open collector outputs with status indicators for process control or alarming.
The unit also has the ability to accept other sensors with 4 to 20 mA output, via the Signet 8058 Signal Converter. The chemical resistant NEMA 4X/IP65 front face is found in both the highly visible field mount or black panel mount instrument, both featuring a self healing window, a standard ¼ DIN cutout and large push buttons for easy navigation. Programming capabilities are available for single point calibration, setting of relays and outputs, and output simulation function for complete system testing. Allows difference calculation (∇P) and offers significant cost savings with independent dual outputs.
