Wet and dust-laden atmospheres
The transmitter is dust and sand tight and protected
against immersion effects as defined by IEC 60529 (2001)
to IP 67 (IP 68 on request) or by NEMA Type 4X.
IP65 with Harting Han connector.
Aluminium and AISI housings as barrel version also comply
to IP 66 as defined by IEC 60529 (2001).
IP66W/IP67W/IP68W as standard for Inmetro certification.
Specification – performance
Stated at reference condition to IEC 60770 ambient
temperature of 20 °C (68 °F), relative humidity of 65 %,
atmospheric pressure of 1013 hPa (1013 mbar), mounting
position with vertical diaphragm and zero based range for
transmitter with isolating diaphragms in AISI 316 L ss or
Hastelloy and silicone oil fill and HART digital trim values
equal to 4 mA and to 20 mA span end points, in linear mode.
Unless otherwise specified, errors are quoted as % of span.
Some performance referring to the Upper Range Limit are
affected by the actual turndown (TD) as ratio between
Upper Range Limit (URL) and calibrated span.
