AutomationDirect Offers Pressure Sensors

AutomationDirect has added ProSense™ pressure switches and transmitters to its growing offering of sensor products. ProSense pressure sensors are designed to monitor system pressure in hydraulic and pneumatic applications, while the vacuum sensors provide an accurate readout of increases and decreases in vacuum systems.

ProSense sensors are smaller and easier to install than traditional mechanical pressure switches. With no moving parts, such as pistons or springs that can stick or break, ProSense pressure and vacuum sensors are a worry-free, solid-state solution to mechanical switches. ProSense offers pressure sensing solutions using capacitive sensing technology and strain gauge technology.

ProSense Pressure SensorsThe compact PTD Series pressure and vacuum transmitters, in robust stainless steel housings, detect system pressure and convert it into an analog output signal for reliable pressure indication. Designed for quick installation and easy setup, pressure transmitter output options include 4 to 20 mA or 0 to 10 Volts, and are available in sensing ranges up to 1,000 psi. Vacuum-style transmitters offer 20 to 4mA or 10 to 0 Volt outputs. The sensors’ ceramic sensing element provides high burst/overpressure protection, and the flexible film circuitry results in excellent shock and vibration resistance.

The PSD series electronic pressure switches feature an extremely durable housing, with 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). Mechanical adjustment dials rotate quickly to establish the setpoint and reset point. The sensor is adjustable without system pressure and supply voltage and does not require calibration. The sensor’s high accuracy and long-term stability (over 50 million switching cycles) ensure the setpoint does not drift. Vibration and shock-resistant, PSD series electronic pressure switches are equipped with LEDs which indicate switching and operating status. The switches provide a dual switching DC output through a micro connector.

All ProSense pressure sensors are cULus and CE approved, and utilize quick-disconnect cables, sold separately.
