The Ametek family of HPT100 of flow-through and single-ended pressure transducers solves problems that the industry’s facilities maintenance technicians, gas suppliers and process engineers have lived with for many years. Issues such as:
Instability and output errors due to Joule-Thompson cooling, operating temperature sensitivity, repeatability and hysteresis.
RFI/EMI induced interferences Signal processing circuit failures Coupling-induced stress errors during installation
AMETEK utilizes the most stable sensor available for UHP transducers, sputtered METAL THIN FILM technology. The gas wetted surfaces are reduced sulfur 316L, with a passivated 7-10RA surface finish and Hastelloy® diaphragm, and are certified to be free of all detectable contaminants. The circuits are isolated from external interferences with RFI/EMI filters and a power limiting circuit which has been agency approved to meet Class I, Div. 1 intrinsic safety are also NEMA 4x rated to meet the demanding needs of outdoor installations. AMETEK supplies the product through its global distribution partner network so each operating facility will receive personal support throughout the life of the gas distribution system.
