0-100MPa PM-T421 Electric Power Pressure Transmitter
Product Introduction:
PPM-T421 pressure transmitters are low-cost, cost-effective civil
and industrial products. This series of products adopts special
structure design, wide pressure range, strong overload capacity,
and safe and reliable. With its excellent reliability, flexibility
and diversity .
The pressure seat of the PPM-T421 transmitter is made of 17-4PH stainless steel single-piece
integrated structure. The integrated stainless steel diaphragm
makes the overload performance much higher than the common cores
such as diffused silicon and ceramics, and its pressure interface
has no welds , No silicone oil or other organic matter, good
sealing performance. The sensor's sensitive components are firmly
sintered on the pressure seat with glass micro-melting technology,
which greatly improves the sensor's performance in high temperature
resistance and vibration resistance, ensuring the long-term
stability, reliability and durability of the transmitter in
industrial harsh environments. In the standard purification
production process, various parameters are strictly controlled. The
entire product has undergone strict testing and aging screening of
components, semi-finished products and finished products, and its
performance is stable and reliable.
