Technical data
Setting timer/
Response time
Analog signal: ≤ 5 ms
Switching output: ≤ 5 ms
Service life 100 million switching changes
Voltage supply
Auxiliary energy
DC 15 ... 35 V
The pressure switch must be supplied by an energy-limited circuit as per 9.3 of the UL/EN/
IEC 61010-1 or LPS as per UL/EN/IEC 60950-1 or class 2 as per UL1310 / UL1585 (NEC or CEC).
The voltage supply must be suited for operation above 2,000 m if the pressure switch is used from
this height.
Power consumption
Max. 45 mA for versions without 4 ... 20 mA output signal
Max. 70 mA for versions with 4 ... 20 mA output signal
Total power consumption Max. 600 mA including switching current
Accuracy information
Accuracy, analog signal
≤ ± 0.5% of the range
Inclusive of non-linearity, hysteresis, zero point and full-scale error (corresponds to error of
measurement as per IEC 61298-2).
Non-repeatability, analog
signal
≤ 0.1% of the range (IEC 61298-2)
Long-term drift, analog
signal
≤ ± 0.1% of the range (IEC 61298-2)
≤ ± 0.2% of the range (IEC 61298-2) for measuring ranges ≤ 0.6 bar (9 psi), ush-mounted
process connection, increased overload protection
Turn down, analog signal
In the range of max. 5:1, the analog output signal can be freely scaled.
If a turn down is set, proportionally increased measurement deviations and temperature errors
apply.
Accuracy, signal output ≤ ± 0.5% of the range
Temperature error in
nominal temperature range
Maximal: ≤ ± 1.5% of the range
Maximal: ≤ ± 2.5% of the range for increased overload protection and ush-mounted versions
Temperature coefcients in
nominal temperature range
Average TC zero point ≤ ± 0.16% of the range / 10 K
Average TC range ≤ ± 0.16% of the range / 10 K
