Low Pressure for Consistency and Safety

Welcome to All Sensors “Put the Pressure on Us” blog. This blog brings out pressure sensor aspects in a variety of applications inspired by headlines, consumer and industry requirements, market research, government activities, and you.

Low Pressure for Consistency and Safety

A liquid propane (LP) powered portable heater can make an enclosed space tolerable and even comfortable when the outdoor temperatures are low. Many systems use pressures in the range of 10 to 20 psi. However, these pressures can reduce the unit’s BTU output as the temperature drops. In contrast, a low-pressure portable heater system such as Dyna-Glo’s Delux 60,000-BTU Portable Forced Air Propane Heater can consistently achieve maximum BTU outputs, even in extremely cold environments. Operating at only 0.5 psi, the unit is also safer. Since the operating pressure is determined by design and not measured during operation, it does not have a pressure sensor. However, in the design verification or quality control processes, a pressure sensor such as All Sensors SPM 401 Series media isolated sensor could be used by manufacturers that make low pressure heaters as well as those that make high pressure heaters.
