SPD905X Piezoresistive Monosilicon Differential Pressure Transmitter SPD905X is a high-performance digital pressure transmitter using MEMS (Micro-Electro-Mechanical System) monosilicon technology worldwide to meet rigorous and demanding industrial applications with optimum accuracy, linearity and repeatability. The monosilicon sensor element is mounted within a capsule and measures the transfer of pressure through the insulated diaphragm and filling fluid. The complete insulation of the encapsulation prevents the sensor from being affected by changes in ambient temperature, electrical interference and mechanical vibration. All this technology enables the SPD905X to easily handle extreme chemical and mechanical situations with strong resistance to electromagnetic interference (EMI) sufficient to respond to the most demanding environments and industrial applications. Through the display and electronic module (via 3 buttons) or via HART communication protocol, the transmitter can be configured in the field or remotely for a new measuring range, definition of a new unit of measurement, type of alarms and type of analog output . The LCD display shows the adjustment parameters and the process variable. The display can be rotated allowing installation in any position. The robust housing has a viewing window for the LCD display and external push buttons which makes it easy to set parameters safely when applied in a classified area. Both the housing and the electronic module have certifications to work in classified areas: - Flameproof (Exd IIC T6) - Intrinsically safe (Exia IIC T4) Main parameters Measuring medium Pressure, level, differential pressure, density, interface, flow Liquid, gas, or steam flow as well as liquid level, density and pressure Disclaimer: all the data used in the product description is not legally binding.
