One Series Safety Transmitter Overview
The One Series Safety Transmitter is a transmitter-switch for monitoring
pressure or temperature and meets the requirements of SIL 2 for random
integrity at HFT = 0, SIL 3 for random integrity at HFT = 1 and SIL 3 for
systematic capability. The One Series Safety Transmitter incorporates UE’s
patented IAW self diagnostics, redundant and diverse signal processing and
software algorithms to detect abnormalities in the process and internal faults.
The design is based on a powerful microprocessor that provides an extremely
fast response time for emergency shutdown situations.
Sensors
- – 316L stainless steel, welded diaphragm, 1/2” NPT (female) process connection, micro-machined piezo-resistive strain gauge silicon element, 0.25 ml silicone oil fill. Maximum media temperature: -40 to 257°F (-40 to 125°C).
- - 316L stainless steel, welded diaphragms, 1/4” NPT (male) process connections, piezoresistive strain gauge silicon element, silicone oil fill. Maximum media temperature: -40 to 257°F (-40 to 125°C).
- – 316 stainless steel 0.25” OD sheath containing a 100 ohm 4-wire platinum RTD element available with epoxy fill (local low temp) or powder fill (remote high temp). Media temperature limits: -328 to 1000°F, intermittent to 1100°F (-200 to 538°C, int. to 593°C) for TH and TT ranges -40 to 500°F (-40 to 260°C) for TR and TL ranges.
