The Keyence AP-34KP pressure sensor is a versatile and reliable solution for measuring pressure in a wide range of applications. This sensor is designed to operate with a pressure range of 145 psi (1.0 MPa) and is suitable for voltages between 12V and 24V.
The AP-34KP pressure sensor is a pneumatic type sensor, which means it measures pressure by sensing the displacement of a diaphragm caused by the pressure being applied. The sensor's diaphragm is made of a rugged stainless steel material, ensuring durability and resistance to corrosion in harsh environments.
The sensor's output signal is a 4-20mA analog signal, which is widely used in industrial automation and process control systems. This signal can be easily integrated into control systems for monitoring and recording pressure data. The sensor also features a built-in temperature compensation circuit, ensuring accurate pressure readings even in varying temperatures.
The AP-34KP pressure sensor is compact and lightweight, with a size of only 55.5mm (L) x 37.5mm (W) x 18mm (H), making it an ideal choice for space-constrained applications. The sensor is also IP67 rated, meaning it is protected against dust and immersion in water, making it suitable for use in challenging environments.
The sensor comes with a variety of mounting options, including a flange mount, a threaded port mount, and a clamp-on mount, allowing for flexible installation in different types of systems. The sensor also features a built-in LED indicator, which provides visual confirmation of proper operation and connection.
The AP-34KP pressure sensor is backed by Keyence's industry-leading customer support and technical expertise, ensuring that customers receive the highest level of service and assistance throughout the entire lifecycle of their sensor. With its robust design, accurate measurement capabilities, and flexible installation options, the AP-34KP pressure sensor is an excellent choice for any application that requires precise pressure measurement.
