Customer Reviews
A simple 2 point calibration curve via the menu would make this 5 stars.An offset would make this 4 stars.Simple FW mods with a few bytes of memory.I don't understand why vendors don't employ this in digital pressure transducers.I would pay 2X $$ if it had this feature.Like:*Good PCB work and mostly adequate wiring (see picture).*Display bright and visible.*Buttons have solid feedback.*Sturdy enclosure.*Most menu functions understandable after translating manual (LuAL is a little confusing)*Internal transformer can be replaced to power off of 24V HVAC system or entire system can be easily modified to run on DC power with short work.*Economical.Dislike:*NEEDS A METHOD FOR ZERO OFFSET. At atmospheric pressure display is reading 0.196 at sea level. Should be 0.101xxx AND/OR have a method to enter a +- OFFSET to be a viable product for low pressure applications. OR make a 0.0 to 0.4 MPA model PLEASE.*Primary transformer wires should have improved protection to prevent shorting to transducer gland under high vibration applications (very thin shrink tubing used).*LuAL function needs more explanation.*FW averaging algorithms could be improved. Unstable for a minute after startup until averages buffers are full.Nice to have:*PSIG (this could be added with an OFFSET however).*2 point calibration in firmware.Overall this may fit many users needs, if you do not need +- 1 PSI accuracy.Does not fit my needs as it stands today. This is unfortunatel as I have many needs for a product such as this.
