The Ceraphant PTC31 is an economical pressure switch with a vacuum-sealed ceramic measuring cell for the measurement and monitoring of absolute and gauge pressure.
Benefits
Excellent accuracy, shortest response time and smallest measuring span
Ceraphire® sensor diaphragm: corrosion-resistant, wear-resistant and highly overload-proof
Built-in switching electronics for decentralized and economical process monitoring and control
Modular connection for fast and flexible installation
Excellent repeatability and long-term stability. The LED digital display module allows on-site checking of the instrument status and retrieval of information
The upper housing can be rotated by 310 ° for convenient reading of the display.
Compliant with DESINA standard, 3-A certified
Application areas
The pressure switch is used to monitor the absolute and gauge pressure of gases, vapors, liquids and dust.
The Ceraphant T PTC31 uses a ceramic sensor and measures pressure in the range from vacuum to 40 bar/600 psi.
Electrical configuration: 1 PNP switch output, dual PNP switch outputs, PNP switch output plus analog output 4…20 mA (active).
