C ASHCROFT' Trust the shield.™ APPLICATIONS: Pulp/paper, waste water, spray booths and all heavy medium and pumping processes FEATURES: • Available with PMC adapter (shown) • Flush-mounted integral 316 stainless steel diaphragm • Stainless steel NEMA 4X enclosure • Current/voltage output The Ashcroft® KX transmitter combines the proven benefits of poly-silicon thin film performance with the utility of a flushmounting sensing diaphragm. Modern low-pressure chemical vapor deposition methods provide simple, stable molecular bonds between the metal diaphragm and a polysilicon strain gage bridge. There are no epoxies or bonding agents to contribute to signal instability or drift. The flush sensing element is provided by an integral, silicone filled stainless steel diaphragm seal. The small sensing area and low internal volume ensure accurate measurement under severe conditions. The polysilicon strain resistors combine very low noise levels with very high signal output. The integral metal diaphragm and polysilicon bridge are virtually unaffected by shock, vibration or mounting position. These transmitters are offered in many standard pressure ranges with either current or voltage output signals. Transmitter performance is directly traceable to the National Institute of Standards and Technology.
