One Series Safety Transmitter Pressure And Temperature Transmitter-Switch

The One Series Safety Transmitter is a transmitter-switch for monitoringpressure or temperature and meets the requirements of SIL 2 for randomintegrity at HFT = 0, SIL 3 for random integrity at HFT = 1 and SIL 3 forsystematic capability. The One Series Safety Transmitter incorporates UEspatented IAW self diagnostics, redundant and diverse signal processing andsoftware algorithms to detect abnormalities in the process and internal faults.The design is based on a powerful microprocessor that provides an extremelyfast response time for emergency shutdown situations.Some applications require a local switch that is capable of initiating anemergency shutdown at the point of measure. This avoids any time lag thatmay occur by sending a signal to a safety PLC and having the PLC initiate theshutdown. This practice can take several (precious) milliseconds. Unique toUE One Series transmitters, the One Series Safety Transmitter can provide theshutdown directly in less than 100 milliseconds, ideal for positive displacementpump applications (for example). This high-capacity safety relay output (SRO)with programmable set point and dead band, handles high voltages and currentto actuate a control valve or shut down a compressor directly and rapidly,something a transmitter alone cannot do.One Series Safety Transmitter Pressure and Temperature transmitter switchCertified for Use in SIL 2 functional safety systems per IEC 61508:20100.5% of full range span, at room temperature2-wire 20-40 VDC @ 4-20 mA (Loop or Fixed Current)0.1% of full range spanLong Term Stability: 0.25% of range/year maximum
