sen0257 incorrect data (half as much as in reality)?

I purchased four sensors and began installing them on the heating system and water distribution system in a shopping center. I immediately noticed that the sensor readings differed from the readings of the analog pressure gauges already installed on the pipes.

SEN0257 shows 325 kPa, but analog water pressure shows 6 ATM

 

I swapped the sensors, but to no avail.

 

I installed the next sensor in a new place and there is the same problem: it shows 250 kPa and the analog pressure gauge shows 4 ATM
