1.1 Safety aspects of the VITO Interfaces & probes
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
VITO-CEPS
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)
Relative humidity (VITO Interface)
Ingress protection (VITO Interface)
Operating temperature (probes)
764 low temp. version
764/767 standard version
764 high temp. version
764 very high temp. version
765/766/768/365 probe
MRT probe
361 low temp. version
361 standard version
361 high temp. version
361 very high temp. version
365 standard version
Note:
Water measurement performance depends on the phase of water and
constitution.
Operation pressure (probes)
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.
