A gauge range all welded stainless steel pressure sensor for research use to measure pressure of helium gas over a range of 0 to 100 psi g from the 1/4 NPT male process connection, and sending the corresponding 4-20mA signal through the M12 connector electrical connection.
The DMP335 pressure sensor is a specialized solution for research applications involving helium gas measurement. Constructed from robust, all-welded stainless steel, this sensor is designed to accurately and reliably monitor helium gas pressure within the 0 to 100 psig range. The all-welded design ensures the integrity of the sensor, preventing leaks and maintaining the purity of the helium gas being measured.
A key feature of the DMP335 is its helium leak test certification. After manufacture, each sensor undergoes rigorous testing to verify its leak-free performance. This certification provides researchers with the confidence that the sensor will not compromise the integrity of their experiments or systems.
The sensor’s 1/4 NPT male process connection ensures compatibility with a wide range of research setups, allowing for easy integration into existing systems. The 4-20mA current output, transmitted through an M12 connector, provides a versatile and industry-standard signal that can be readily interfaced with data acquisition systems, controllers, and other instrumentation commonly found in research laboratories.
The DMP335 is particularly well-suited for applications where precise monitoring of helium gas pressure is critical. This includes research involving:
- Leak detection in high-vacuum systems
- Monitoring helium gas pressure in cryogenic applications
- Controlling helium gas flow in gas chromatography experiments
- Ensuring the integrity of helium-filled systems in particle physics research
The DMP335‘s combination of accuracy, reliability, and specialized testing makes it an indispensable tool for researchers working with helium gas.
