Review MURPHY Pressure Sender 0-400 Psi 2-wire Ungrounded 1/8 Npt

The Murphy 05702565 ES2PMK-400 Pressure Sender is a reliable and accurate 2-wire, ungrounded pressure transducer designed for use in a wide range of industrial applications where pressure measurement is essential. This versatile pressure sender can measure pressures ranging from vacuum to 400 psi (27.6 bar) and is equipped with a 1/8 NPT thread connection.

The ES2PMK-400 is a 0-400 psi ungrounded, 2-wire sensor, which means it transmits both the pressure measurement signal and the reference signal on separate wires. This eliminates the need for a ground wire, making the installation process simpler and reducing the risk of ground loops. The sensor's compact and rugged design makes it suitable for installation in harsh environments.

The pressure sender utilizes a high-precision, stainless steel diaphragm for measuring pressure changes. The diaphragm is connected to an internal strain gauge that converts the mechanical pressure input into an electrical signal. The sensor's output is a 4-20mA current signal, which is widely used in industrial control systems due to its high accuracy and linearity.

The ES2PMK-400 is calibrated at the factory to ensure precise and accurate pressure readings. It is also temperature compensated to maintain accuracy in a wide temperature range, typically between -20 C and 70 C (-4 F and 158 F). The sensor's electrical connections are protected by a durable, IP65-rated housing, which shields them from moisture and other environmental contaminants.

This Murphy pressure sender is easy to install, requiring only the connection of the 2 wires to the power and signal terminals on the control system. It is designed for use in industrial applications, such as process control, HVAC systems, and hydraulic and pneumatic systems, where precise and reliable pressure measurement is essential.

In summary, the Murphy 05702565 ES2PMK-400 Pressure Sender is a high-performance, 2-wire, ungrounded, 1/8 NPT transducer that accurately measures pressure in the range of 0-400 psi. With its rugged design, wide temperature range, and easy installation, it is an ideal choice for industrial applications where precision and reliability are key.
