7532 Technical data

Inventory Control Ver- sions

All device types can be delivered as "Inventory Control Versions" with a reduced accuracy of ± 3mm (under reference conditions).

To these versions, the calibration certificate or custody transfer type approval is NOT attached.

The "Inventory Control Versions" can be selected by choosing the option »R« in feature »70« in the order code section »Custody transfer approvals« on page 8.

Environment

Ambient temperature	Ambient temperature for the transmitter:
range	• Standard: -40 °C … +80 °C (-40 °F … +176 °F)
	• For calibration to regulatory standards: -25 °C ... +60 °C (-30
	°F…+140 °F)
	With Tu<-20 °C and Tu>+60 °C the operability of the LC-display is
	reduced.
	A weather protection cover should be used for outdoor operation if
	the instrument is exposed to direct sunlight.
Storage temperature	-40 °C ... +80 °C (-40 °F … +176°F)
Climate class	DIN EN 60068-2-38 (test Z/AD)
Degree of protection	• housing: IP 65, NEMA 4X (open housing: IP20, NEMA 1)
	• antenna: IP 68 (NEMA 6P)
Vibration resistance	DIN EN 60068-2-64 / IEC 68-2-64: 20…2000 Hz, 5 (m/s²)²/Hz
Cleaning of the antenna	See »Technical Information« TEC028
Electromagnetic com-	• emissions according to EN 61326; equipment class B
patibility	• compatibility according to EN 61326; appendix A (industrial area,
	10 V/m) and Namur recommendation EMC (NE 21).
