1) Response time: ≤10 ms at medium temperatures below <-30 °C
2) Including non-linearity, hysteresis, zero point and full scale error (corresponds to error of measurement per IEC 61298-2). Calibrated in vertical mounting position
with process connection facing downwards.
3) The existence of strong electromagnetic fields in a frequency range of < 2.7 GHz can result in increased measured errors up to 1 % of span. Do not install the
instruments in the vicinity of strong electromagnetic sources of interference (e.g. transmitting device, radio equipment), or use sheath current filters where applicable.
When designing your plant, take into account that the stated values (e.g. over pressure safety) apply
depending on the material, thread and sealing element used.
