Technical data Micropilot S FMR531 with HART/4...20 mA
84 E Hauser
Non-repeatability 0.3 mm (1/64")
Hysteresis 0.3 mm (1/64")
Resolution • digital: 0.1 mm
• analog: 0.03 % of measuring range
Settling time Typical 15 sec
Long-term drift The long-term drift is within the specified accuracy.
Influence of ambiente
temperature Within the specified accuracy according to OIML R85
Software reliability The software used in the radar instrument Micropilot S fulfills the requirements of OIML R85. This
particularly includes:
• cyclical test of data consistency
• non-volatile memory
• segmented data storage
The radar instrument Micropilot S continuously monitor the compliance with accuracy
requirements for custody transfer measurements according to OIML R85. If the accuracy cannot be
maintained, a specific alarm is generated on the local display and via the digital communication
(see Page 33).
Inventory control versions All device types can be delivered as "Inventory Conctrol Versions" with a reduced accuracy of ± 3
mm (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 the order code section
»Custody transfer approvals« on Page 9.
Reaction time The reaction time depends on the parameter settings (min. 1 s). In case of fast level changes, the
instrument needs the reaction time to indicate the new value.
10.1.6 Operating conditions: Environment
Ambient temperature range Ambient temperature for the transmitter:
• Standard: -40 °C ... +80 °C (-40 °F…+176 °F)
• For calibration to regulatory standards: -25 °C ... +55 °C (-30 °F…+140 °F)
With T
u
<-20 °C and T
u
>+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 68, NEMA 6P (open housing and removed liquid crystal display: IP20, NEMA 1)
• Antenna: IP 68 (NEMA 6P)
