Relative pressure transmitter PTX 400

absolutesilicon4-20 mA

The PTX 400 series of pressure, temperature and combined pressure/temperature transmitters have been specifically designed for long term use in subsea locations. It enables accurate process measurements to be made directly on subsea production equipment. The sensor design is based on API6A performance requirement PR2 and product specification level PSL3. The PTX 400 utilizes our proprietary Druck micromachined piezo resistive silicon pressure measuring technology continually developed and proven for 30 years. In addition, for the TTX and PTTX variants, precision temperature measurement capability over a wide operating range is provided by a fully integrated high performance platinum resistance type sensor. Pressure ranges are available up to 1035 bar/15,000 PSI as standard with proof pressure at 1.5 x full scale range and secondary pressure containment in excess of 1553 bar. All units in the 400 series are suitable for continuous use in excess of 25 years, when immersed in saltwater depths of up to 3360 metres. Features • High reliability and excellent long term stability • All welded construction, high containment • Customized designs available. Options include CANBus, Modbus and 4-20mA output • Nose lengths between 60mm to 300mm (with protection cap) or 13mm to 300mm (without protection cap) • Proprietary Subsea Connector, M25 MKII OMNITEC or JIC backend • SIL (Safety Integrity Level) versions available
