Watson Smith IP Converter NPT 1/4 Female 2.5NL/min Flow Rate 4-20 mA Input Signal 0.2 bar to 2 bar EX140 01PK4EE1

Watson Smith EX140 01PK4EE1 is a high-performance IP converter designed for precise electronic current-to-pressure conversion in pneumatic systems. Featuring a 4-20 mA input signal capability, this converter achieves a maximum flow rate of 2.5 NL/min and delivers output pressures from 0.2 bar to 2 bar. The robust construction with an NPT 1/4 female connection thread ensures compatibility with standard pneumatic fittings.

Engineered for demanding industrial and process environments, this unit operates reliably within a broad temperature range of -40°C to 85°C and carries an IP66 rating, making it resistant to dust and water ingress. The device includes fail-safe operation functionality to drop output pressure safely to zero upon input signal loss, greatly enhancing operational safety.

Watson Smith’s IP converter is ATEX-certified, suitable for hazardous area installations, and is ideal for controlling cylinders, valves, valve positioners, relays, brakes, and clutches in industrial automation contexts. It supports precise adjustment of zero and span from the front face of the instrument for ease of calibration.

Installation flexibility is enhanced by its compact size (161 mm height, 116 mm length, and 94 mm width) and field-replaceable air filter. The product is designed to function with oil-free, clean, and dry air filtered to 5μm or less, and requires inlet pressure at least 0.7 bar above output pressure to maintain optimal performance.

Supports 4-20 mA electrical input signal for precise control. Maximum flow rate of 2.5 NL/min suitable for pneumatic applications. NPT 1/4 female connection with standardized thread for reliable fitting. Wide operating temperature range from -40°C to 85°C for versatile environments.

Robust IP66 rating ensures protection against dust and water ingress. Equipped with ATEX certification for safe use in hazardous areas. Minimum outlet pressure of 0.2 bar and maximum outlet pressure of 2 bar ensure precise pressure regulation.

Fail-safe operation provides output pressure drop on input signal loss for safety. Compact dimensions: 161mm height, 116mm length, and 94mm width. Designed for industrial, process control, and pneumatic valve positioner applications.

This IP converter presents an essential component for pneumatic air preparation systems, providing accurate pressure modulation in industrial automation and process control scenarios. Its robust design and certifications ensure reliable and safe operation under demanding conditions.
