8450 Pressure Transmitter
The Signet 8450 Pressure Transmitter is a unique instrument that offers local or remote display with current and relay outputs. The instrument is available in field and panel mount configurations, single or dual channel input and is equipped with a 4 to 40 mA output, fullt scaleable and reversible for each input channel. Configuration flexibility is maximized with optional relays for process control and alarming. The unit also has the ability to accept other sensors with 4 to 20 mA output, via the Signet 8058 Signal Converter.
Chemical resistant NEMA 4X/IP65 packaging options include highly visible field mount or black panel mount instrument, both featuring a self-healing window, a standard 1/4 DIN cutout. Dual input version allows difference calculation (ΔP) and offers cost savings with independent dual outputs.
Fields of Application:
- Pump, Filter or Pipe Protection
- Pressure Regulation/Monitoring
- Over or Under Pressure Alarm
- Pump Servicing
- HVAC
- Chemical Processing
- Scrubber Systems
- Water Management
- Irrigation Systems
Advantages:
- Digital (S3L) input for stable and reliable reading
- psi, Bar, or kPa display
- Integral or remote mounting
- Single point calibration
- Dual input/output option
- Output simulation function for complete system testing
- Relay option
- Output scaleability
- NEMA 4X/IP65
Standards:
- CE
- UL
- CUL
- RoHS compliant
