SECTION I SAFETY APPROVALS
Ametek UHP Transmitter Safety Approvals:
The model HPT 100 transmitters with the appropriate suffixes have been declared as
conforming to the following safety classes: (See model code structure section I, pg. 1-1)
Intrinsic Safety/Non-Incendive: Class I, Groups A, B, C, D (Agency Approval Suffix 1)
Division II : Class I, Div 2, Groups A, B, C, D (Agency Approval Suffix 2)
NEMA/IP Rating: Type 4X/IP56 ( Electrical Connection Suffix P, N or C)
Approval has been granted by Canadian Standards Association. In addition to Canadian
approval, CSA is listed as a Nationally Recognized Testing Laboratory (NRTL), which is
accredited by the Occupational Safety and Health Administration (OSHA) under the U.S.
Department of Labor. This allows CSA to Certify electrical products to U.S. Standards.
The CSA/NRTL mark is recognized throughout the U.S. at federal, state and local levels,
and is equivalent to any agency mark in the U.S. with respect to acceptance by regulatory
authorities. The intrinsic safety unit also carries LCIE approval with the EExia symbol,
allowing full recognition in Europe.
Intrinsic Safety/Non-Incendive(CSA)
: A suitable barrier is required. Either entity or
system approval parameters can be followed to determine which barrier(s) to use.
Consult section on installation instructions (Drawing K750525 for 4 - 20 mA. or
K750531 for 0-5V).
Entity parameters: 4-20 mA;
Vmax = 28 Volts, Imax = 100 mA,
Ci = 65nf, Li = 40 uH.
0-5V
; Vmax = 28 Volts, Imax = 100 mA, Ci = 76nf, Li = 50 uH.
Temperature Code Ratings: 4-20 mA(System Approval);
T5 at 40°C max. ambient
or T4 at 85°C max. ambient.
4-20 mA(Entity Approval);
T3C at 40°C max. ambient or
T2C at 85°C max. ambient.
0-5V(System Approval);
T6 at 40°C max. ambient or T4 at
85°C max. ambient.
0-5(Entity Approval);
T3C at 40°C max. ambient or T2C at 85°C.
Only pigtail models with suffixes P, N or C are rated Type 4X.
Intrinsic Safety (LCIE):
A suitable barrier is required. The same entity parameters
listed for CSA apply.
Temperature Code Ratings: 4-20 mA. or 0-5Vdc:
T4 at 40°C
max. ambient or T3 at 85°C max. ambient. The associated apparatus (safety barrier) must
not exceed the following limits: Uo < = 28 V; Io < = 100 mA.; Po < = 0.7 w. When
installing the enclosure, it must be isolated from ground surfaces or shall be at the same
earth potential as the barrier earth ground.
Division 2
: Input rated 12-30Vdc for outputs 4-20 mA. or 0-5Vdc. Maximum temperatue
85°C ambient; The HPT 100 models except with Electrical Connection Suffix “C” are
certified as a component for use
only
in other equipment (gas cabinet, for example) where
the suitability of the combination is to be determined by the authority having jurisdiction.
The intent is to protect the cabling from shorting or opening by use of a suitable
protective enclosure.
