Versatile Pressure Sensing for Demanding Applications

HST Pressure Sensors are tailored for rigorous industrial, automotive, and HVAC applications. With a pressure range spanning 0 to 20 bar and fast response times, they are suitable for monitoring and controlling critical systems. The robust stainless steel construction, coupled with threaded mounting, ensures resilience and reliable performance even in harsh conditions.

High Accuracy and Flexible Output Options

These sensors feature capacitive and resistive measurement theories, offering analog voltage output (0.5V 4.5V) for precision control. The ratiometric signal enhances compatibility with modern control systems, while selectable accuracies of 1.5 %FS, 0.5 %FS, or 0.25 %FS meet varying requirements, making them suitable for both general and high-precision tasks.

FAQs of HST Sensors:

Q: How is the HST pressure sensor installed in various environments?

A: The HST pressure sensor utilizes a threaded mounting design, enabling secure and straightforward installation onto compatible industrial, HVAC, or automotive equipment. Its IP65 rating ensures reliable operation even in challenging or outdoor environments.

Q: What benefits does the stainless steel construction provide for these sensors?

A: The use of stainless steel enhances the sensors durability, making it resistant to corrosion, mechanical shocks, and harsh operating conditions. This translates to longer service life and reliable measurement under strenuous environments.

Q: When should the different accuracy options (1.5 %FS, 0.5 %FS, 0.25 %FS) be selected?

A: The accuracy requirement depends on the applications criticality. High-precision control systems may demand 0.25 %FS accuracy, while general monitoring can utilize the 1.5 %FS or 0.5 %FS options for cost-effectiveness.

Q: Where can HST pressure sensors be applied effectively?

A: These sensors are suitable for a range of industries, including industrial automation, HVAC systems, and automotive pressure monitoring. Their wide temperature range and ingress protection accommodate both indoor and outdoor installations.

Q: What is the typical process for integrating the sensor into a control system?

A: Integration involves mounting the sensor using its threaded fitting, connecting via Packard, M12, or cable connectors, and linking the analog output (0.5V 4.5V) to the systems measurement interface. The 5V DC supply and low power consumption simplify compatibility with standard controller circuits.

Q: How does the sensors lifecycle of one million cycles benefit users?

A: With a tested lifecycle exceeding one million cycles, these sensors provide long-term reliability and reduce the need for frequent replacements, minimizing maintenance costs in high-use or critical systems.
