IP65 protection is given when the connector is locked with a rubber washer. For proper function the gage port is vented to the atmosphere through the connector/cable assembly. Thus the cable end must have access to the ambient pressure. 2. The minimum supply voltage is directly proportional to the load resistance seen by the transmitter. For more details see the load limitation diagram. 3. Proof pressure is the maximum pressure which may be applied without causing damage to the sensing element. 4. Thermal effects tested and guaranteed from 0 to 60C relative to 25C. All specifications shown are relative to 25C. 5. Non-linearity refers to the Best Straight Line fit measured for offset, full scale span and 1/2 full scale span. 6. Long term stability is the change in output after one year or 1 million pressure cycles. 7. Span is the arithmetic difference in transmitter output signal measured at zero pressure and the maximum operating pressure. 8. Test are in accordance with EN61000-6-2, April 1999. 9. CE-labelling is in accordance with 89/336/EEC. 10. The pressure transmitters must not be used as safety accessories according to article 1, 2.1.3 of the directive 97/23/EC. 11. BAM certification-No: BAM/ZBA/001/07. The BAM certificate refers only to the burn-out safety of the materials in oxygen service. 1.
