1.1 Safety aspects of the VITO Interfaces & probes
Warning
Do not use the instrument for anything else than its intended purpose.
The housing of the 762 VITO Interfaces & 764, 765, 766, 767 or 768 temperature and/or
water bottom probe and MRT probe is intrinsically safe, certified by KEMA (Netherlands):
VITO-MTT & VITO-LT : II 1/2 G EEx ia IIB T4, KEMA 01ATEX1212X
VITO-MRT : II 1/2 G EEx ia IIB T4, KEMA 04ATEX1225X
VITO-CEPS : Zone 0/1 Ex ia IIB T4, IECEx KEM 05.0014X
The VITO MPT probe is a passive component and can be considered as simple apparatus
when used in Intrinsically Safe circuits in accordance with the following:
• EN IEC 60079-11, clause 5.7
• NEC (National Electrical Code) Article 504 (Intrinsically Safe Systems) 504.2
(Definitions) Simple Apparatus
The VITO MPT probe is Intrinsically Safe and can be used with the FlexLine radar gauge
(direct connection up to 6 Pt-100 elements) or with the VITO-MRT interface.
The environmental conditions for the VITO interfaces & probes are:
Ambient temperature (VITO Interface) : -40 to 60 °C (-40 to 140 °F)
Relative humidity (VITO Interface) : 0 –100%
Ingress protection (VITO Interface) : IP 65
Operating temperature (probes)
764 low temp. version : -200 to 70 °C (-328 to 158 °F)
764/767 standard version : -55 to 135 °C (-67 to 275 °F)
764 high temp. version : -55 to 200 °C (-67 to 392 °F)
764 very high temp. version : -55 to 250 °C (-67 to 482 °F)
765/766/768/365 probe : 0 to 100 °C (32 to 212 °F)
MRT probe : -50 to 200 °C (-58 to 392 °F)
361 low temp. version : -200 to 50 °C (-328 to 122 °F)
361 standard version : -50 to 120 °C (-58 to 248 °F)
361 high temp. version : -50 to 200 °C (-58 to 392 °F)
361 very high temp. version : -20 to 250 °C (-4 to 482 °F)
365 standard version : -20 to 120 °C (-4 to 248 °F)
Note:
Water measurement performance depends on the phase of water and
constitution.
Operation pressure (probes) : 5 bar / 500 kPa (72 psi) (76x probes)
: 6 bar / 600 kPa (87 psi) (36x probes)
Caution
The 762 VITO Interface is an instrument with intrinsically safe output/input circuits.
Modification to the instrument may only be carried out by
trained personnel which is authorized by Honeywell Enraf.
Failure to adhere to this will invalidate the approval certificate.
