Stainless Steel Pressure Sensors EA and EAF Models EA Series FEATURES • Amplified output which eliminates the cost of external amplifiers • Large choice of pressure ranges to meet a variety of application needs • Rugged, lightweight Valox case • Microprocessor compatible 1 Vdc to 6 Vdc or 1 kHz to 6 kHz span • Manifold mounting for ease of installation TYPICAL APPLICATIONS • Agricultural sprayers and dusters • Air conditioning and refrigeration • Engine controls and monitors • Environmental control systems • Compressors • Hydraulic controls • Pneumatic controls • Process control equipment • Robotics • Transmissions • Water management PRESSURE TRANSDUCER The EA manifold mount is designed for OEM uses requiring high output and corrosion resistance. It has operated through millions of pressure cycles without damage and is well-suited for the high cycle rates found in automatic equipment, robots, and hydraulic systems. The EA has been approved by Underwriters Laboratories as a component in float and pressure operated motor controllers (file #E93356). Its pressure port, amplifier, and voltage supply regulator are packaged in a Valox case. A mating electrical connector is included with this low price transducer. The EAF version outputs a low frequency signal which is ideal for electrically noisy environments as well as applications requiring long distance signal transmission or an interface to a microprocessor. The output signal is a frequency modulated square wave set from 1 kHz to 6 kHz.
