Section 11 Dover Magnetostrictive Probe (DMP)
11.1 DMP-IS Technical Characteristics
RS 485 Serial Communication for Multi-point Connection
l Power supply 12 VDC through an intrinsically safe barrier.
l Consumption <20 mA @ 12 Vdc normal functioning
l Connection cable: hydrocarbons resistant, suitable for underground pose with insulation 0,6-1 KV, 2
shielded and twisted pairs, section of the power cable pair of at least 1 mm2.
l Type of cable supplied by Start ltaliana for backbone connection:
LiYstCYY INSULATION LEVEL 4 (0,6/1 KV) - (2x0.25mm2) + (2x1 .00mm2) CEI 20-2211 IEC
60332-3A ENI 00.181.00
l Type of cable supplied by Start ltaliana with the probe (1.5mt):
LiYstCYY INSULATION LEVEL 4 (0,6/1 KV) - (4x0.25mm2) CEI 20-2211 IEC 60332-3A ENI
00.181.00
l Maximum transmission distance: up to 2 Km based on standard of RS485 interface.
Measurement Characteristics
l Electronics based on a Microprocessor
l Support telediagnostics and telemaintenance (only wired version RS485)
l Possibility to configure remotely the functional parameters
l In case of maintenance the internal part of the sensor (wave guide) can be removed without degas the
tank, especially useful for LPG applications where the tanks are in pressure.
l Tank connection:
n Not needed if probe is inserted into a riser with internal diameter 2"
n 2" sliding connection as standard.
n Other type of optional connections under request (nippled fixed, flanged, ... )
l Stainless steel and composite caps case, IP68.
l Probe shaft Stainless Steel AISI 304 / 316
l Measurement range: from 200 mm. to 5000 mm.
l Data transmitted:
n Product level in 0.01 mm
n Water level in 0.01 mm
n Medium temperature detected through digital temperature sensor placed along the probe shaft
(max 5)
n Density range (option): 600-900 Kg/m3
n Density Accuracy (option): 3 Kg/m3
n Measurement accuracy: < 0.2 mm.
