The 4400 and 4600 hammer-union pressure transmitters are designed for use in hazardous areas, where pressures can reach 20,000 psi. Available with intrinsically safe or explosion-proof approvals, these transmitters have been laboratory- tested for shock and vibration resistance, and are field-tested for the most extreme ambient conditions. Employing a thick Inconel 718 diaphragm and silicon strain gages, these transmitters experience less drift, even in longterm service, says the company. A cage around the pressure transmitter is designed to protect the sensor and mating connector, allowing for proper drainage in flooding situations. — American Sensor Technologies, Inc., Mt.
