This IMP-LR configuration is a specialized pressure sensor designed for low-pressure steam applications with a maximum pressure of 5 psi. This makes it ideal for monitoring steam pressure in smaller systems where precise control is essential, such as laboratory autoclaves, food processing steamers, and textile manufacturing equipment. These applications often require accurate pressure monitoring to ensure product quality, safety, and process efficiency. The 5 psi range provides the necessary sensitivity for these low-pressure environments.
A standout feature of this sensor is the integrated 300°F cooling element. This element allows the sensor to operate reliably in high-temperature steam environments, protecting the sensitive internal components from heat damage. This is particularly important in applications where the sensor is in direct contact with steam, such as in the steam lines of a compact boiler or within a steam sterilizer. The cooling element ensures accurate readings and extends the sensor’s lifespan, even with continuous exposure to high temperatures.
The sensor’s 1/4″ NPT male process connection is a standard fitting in many steam systems, simplifying installation and ensuring compatibility with existing infrastructure. This threaded connection provides a secure and leak-free seal, crucial in steam applications where safety is paramount.
This IMP-LR utilizes a 4-20mA analog output signal, a widely accepted standard in industrial automation. This allows for easy integration with PLCs, SCADA systems, and other monitoring devices, enabling real-time pressure monitoring and process control. This capability is essential for maintaining optimal steam pressure in applications like vulcanizing equipment and composite curing ovens, where precise pressure control is critical for product quality and consistency.
