Description
The PTX 400 enables accurate process measurements to be made directly on subsea wellheads and production manifolds. The sensor design is based on API performance requirement PRI and product specification level PSL3.
The PTX 400 utilizes micromachined piezo resistive silicon pressure measuring technology continually developed and proven over decades. 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 to 690 bar as standard with proof pressure at 1.5 x full scale range and secondary pressure containment in excess of 1035 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 3000 meters.
