FAQ

Question
I need to protect a pressure transmitter from power surges and spikes. The model of the transmitter is: 626-09-GH-P1-E1-S1
Answer
If you are worried about power surges and spikes, we recommend that you use a regulated power supply in your system. See our Model BPS-005 low cost DC regulated power supply.

Question
Series 672 Low Pressure Transducer, is this pressure transmitter suitable for use with Natural Gas? The specs just mention ‘suitable liquids and gases”, but I don’t see a list of what is suitable.
Answer
No, the 672 series low pressure transducer is not suitable for natural gas. It is not explosion proof nor compatible with combustible gases or liquids. As an alternative, depending on the range you need, I would recommend the 636, 3100, 3200G, or IS626 series pressure transmitters.

Question
I am using a differential pressure transmitter model 629-02-CH-P2-E5-S1-LED to measure differential pressure of water. How do I convert the 4-20 mA signal to the differential pressure reading?
Answer
The 4-20 mA output from the 629 is linear over the range, which in this case is 0-10 PSID. Therefore, a 4 mA output will coincide with a differential pressure of 0 PSID, and a 20 mA output will coincide with a differential pressure of 10 PSID with a linear relationship between those two points. With that information, you should simply be able to scale your receiver accordingly.

Question
What does UFL displayed on the Dwyer Series 626/628 mean? The input Voltage is correct and it appears to be piped correctly, but my display says UFL and my output to my controller’s input is -0.285vdc.
Answer
UFL indicates underflow.

Question
I have a 626 pressure transmitter I want to use in 4-20 mA output mode. Trying to figure out what resistance I need. Two questions:
1) What are the units for the result of Rl-max = (Vps – 10)/20 mA DC? For a 12v PS I get 0.1. Is that ohms, Kohms or what? and
2) Does it matter which let of the receiver (+ or -) input the resistance is placed?
Answer
If you use the equation RL-max=(Vps-10)/20mA DC without converting the 20mA to Amps then the results units will be in Kohms. The .1 that you calculated is in Kohms, so you will be to convert that to 100 ohms.
