Digital Overpressure Transmitters with Display, Series RTM, RTM-M for Accurate Pressure Measurement

Microelectronic gauge pressure transmitters with digital indication RTM, RTM-M series Optimal metrological and operational characteristics of transmitters, such as stability, reproducibility and noise immunity of the output signal, are achieved on the basis of application of a sensing element made of monocrystalline silicon, located on a sapphire membrane and a specialised electronic circuit of a high degree of integration with digital signal processing. The high overload capacity of the transducers is achieved by using a double-layer sapphire-titanium membrane with monocrystalline silicon strain gauges ("silicon-on-sapphire technology"). The monocrystalline sapphire membrane is an ideal elastic element and, when combined with titanium, becomes a leader in terms of deformation. The high degree of reliability of the sensing element and electronic circuitry does not require correction of the output range during operation. Digital c...
