Product Description

0.5% Accuracy, NEMA 4X Enclosure

The Series 629 Differential Pressure Transmitter monitors differential pressure of air and compatible gases and liquids with 0.5% accuracy. The design employs dual pressure sensors converting pressure changes into a standard 4-20 mA output signal for two wire circuits. Small internal volume and minimum moving parts result in exceptional response and reliability. Terminal block zero and span adjustments are easily accessed under the top cover. The Series 629
Differential Pressure Transmitter is designed to meet NEMA 4X (IP66) construction.

Product Applications

Monitor Differential Pressure Across:
Flow Elements
Heat Exchangers
Filters
Pumps
Coils

FAQ

Question

We have a defective 629-04-CH-P2-E5-S1-3V DP sensor. The technician only wants to replace “just the sensor”, not the entire manifold assembly. Can you give me the part number for this sensor?

Answer

Here is the part number you could use to replace just the sensor: 629-04-CH-P2-E5-S1. The “-3V” at the end of the model number is the valve manifold option. For any unit just order the model number before the “-3V” as a replacement pressure transmitter.

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.
