Introduction |
|
|
|
|
Functional Specifications |
|
|
|
IME Model 8080HT is a
digital, PC/Hand-Held programmable, isolated |
|
Sensor |
|
|
|
2-wire transmitter with
HART® protocol.
The unit converts 8 types of |
|
|
|
|
|
thermocouples; 5 types of
RTDs, configured as 2, 3 and 4 wires; |
|
Thermo Sensor Type B, E,
J, K, N, R, S, T, Cu50, Cu100, |
|
|
|
potentiometer, resistor
and millivolt inputs into process current loop. |

IME Model 8080HT
Universal Input Transmitters are designed for use in |
|
Output Signal |
|
|
|
|
process industries where
vibration, inclement weather and corrosive |
|
|
|
|
|
atmospheres prevail. The
electronics are enclosed in a copper-free epoxy |
|
4~20mA with HART® protol ( 2 wire) |
|
|
|
|
|
coated Aluminum housing
and for more aggressive environments, a SS316 |
Optional Output |
|
|
|
housing is optionally
available. The housings meet the requirements of |
|
|
|
|
|
NEMA 4X, and are
certified Explosion Proof by FM/CSA. |
|
|
5V, 0.7mA |
|
|
|
|
|
|
|
|
|
|
Isolation |
|
|
|
Exceptional digital accuracy of typical +/-0.1oC is provided for
all the |
|
|
|
|
|
sensors regardless of the
calibrated span. Extremely accurate cold-junction |
500V AC between input and
output |
|
|
|
|
|
|
temperature measurement provides
precise compensation throughout the |
|
Burnout Protection |
|
|
|
entire ambient range. The unit also
accurately measures and compensates |
|
|
|
|
the RTD sensor leads in the 3-wire
connection. |
|
|
Upscale / Downscale
Programmable |
|
|
|
|
|
Supply Voltage |
|
|
|
The transmitter is fully
configurable by connecting to a PC or a Hand-Held. |
|
|
|
|
The configuration
parameters are stored in a non volatile memory. |
|
12~45V DC |
|
|
|
|
|
|
|
|
Operating Temperature |
|
|
|
|
Detection of sensor breakage or
disconnection of input leads, forces the |
|
Circuit Board: -40~+85oC |
|
|
|
output to a pre-defined up/down
scale value. The unit continuously monitors |
LCD: -20~+70oC |
|
|
|
|
|
|
the sensor and
automatically returns to normal operation mode when the |
|
Weight |
|
|
|
sensor is recovered. |
|
|
|
|
|
|
|
|
0.9Kg (2LBS) for Aluminum
unit and 1.4Kg(3LBS) for SS316 Unit |
|
|
In applications where no local
indication is required, the tempered glass |
|
Material of Construction |
|
|
|
cover is replaced by a
solid cover and no LCD indicator is provided. |
