Accuracy/temperature error Accuracy class
According to EN837-1 Class 1
0-6 bar < 0.4% per 10°C of full scale reading 0-10 bar < 0.4% per 10°C of full scale reading
Accuracy
When the temperature of the pressure element rises above +20 °C add the accuracy error and when it falls below +20 °C subtract the accuracy error. Note: These errors are computer generated and for guidance only.
