Important
The lower range limit (LRL) for 265Vx is absolute 0 for all
measuring ranges.
Span limits
Maximum span = URL = Upper range limit
265Dx
Linear/freely programmable characteristic: Within the range
limits, may be adjusted up to ± upper
range limit
Sample setting: -400 ... 400 mbar
Square root characteristic: Sample setting: 0 ... 400 mbar
(Recommendation for square root function:
At least 10 % of upper range limit
(URL)).
265Vx
Linear/freely programmable characteristic: Sample setting:
0 … 400 mbar abs.
To optimize performance characteristics, it is recommended that you
select the transmitter sensor with the lowest turndown ratio.
Zero suppression and elevation
(265Vx: Zero suppression only)
The zero position and span can be set to any value within the range
limits listed in the table if:
- Set span ≥ minimum span
Damping
Adjustable time constant: 0 … 60 s
This is in addition to the sensor response time.
Second sensor for absolute pressure measurement (265Dx)
Measuring range: 41 MPa, 410 bar, 5,945 psi
(0.6 MPa, 6 bar, 87 psi for sensor code A)
Warm-up period
According to technical data, ready for operation in ≤ 2.5 s after
switching on the transmitter, with minimum damping.
Insulation resistance
> 100 MΩ at 500 VDC (between terminals and ground)
