Stainless steel construction - Import export

Reliable, accurate and offering superior senstivity, repeatability and speed of response. The SDT-Ex is suitable for continuous measurement of trace moisture in industrial process gases. This 3 wire, 4-20 mA, loop powered dewpoint transmitter utilises the ultra high capacitance SHAW moisture sensing technology and is certified intrinsically safe to ATEX and IECEx standards. Suitable for use in hazardous areas using a signal isolator and ideal for hydrocarbon, petrochemical and hydrogen applications. The SHAW SDT-Ex incorporates the unique AutoCal function designed by SHAW, allowing users to ensure accuracy between laboratory calibrations. Fully self-contained within a robust housing, the stainless steel construction provides weatherproof protection to IP66 (NEMA 4X). The output is configurable in 5 different units and various dewpoint ranges are available covering an overall range from -100 °C to +20 °C (-148 °F to +68 °F) dewpoint with an accuracy of ±2 °C (±3.6 °F) dewpoint.

Alloy 17-4 PH is a chromium-copper precipitation hardening martensitic stainless steel with Cu and Nb/Cb additions. 17-4PH Stainless Steel combines high strength, hardness (up to 572°F / 300°C), and moderate corrosion resistance. Alloy 17-4 PH withstands corrosive attacks better than any of the standard hardenable stainless steels and is comparable to Alloy 304 in most media. The alloy is subject to crevice or pitting attack if exposed to stagnant seawater for any length of time, although it is corrosion resistant in some chemical, petroleum, paper, dairy and food processing industries(equivalent to 304L grade). Mechanical properties can be improved (high strength and superior corrosion resistance) when precipitation hardened from Condition A to one of the Condition H tempers. We supply 17-4 PH in the H1150D condition. This is double aged at a temperature between 1140° F and 1160° F for 3.75 hours to 4.
