PRESSURE SWITCHES AND TRANSMITTERS
AutomationDirect has added ProSense pressure switches and transmitters to its sensor products. ProSense pressure sensors are designed to monitor system pressure in hydraulic and pneumatic applications, while the vacuum sensors provide a display of increases and decreases in vacuum systems. The sensors are said to be smaller and easier to install than traditional mechanical pressure switches. Units employ capacitive sensing technology and strain gauge technology.0
The compact PTD series pressure and vacuum transmitters are available in sensing ranges up to 1000 psi. Vacuum-style transmitters offer 20 to 4 mA or 10 to 0 V outputs. The PSD series electronic pressure switches feature a 316 stainless steel process connection and gas-tight measuring cell to reliably detect gas and liquid pressure. The switch withstands aggressive media and detects pressure ranges up to 5800 psi (400 bar).
