two wire smart transmitters field mounted

IME Model 8088TR is a digital, PC programmable, galvanically isolated 2-wire smart transmitter. The unit converts:
  - 13 types of thermocouple sensors
  - 12 types or RTD sensors, configured as 2, 3, and 4 wires
  - potentiometer, resistor and millivolt inputs
into process current loop. A 24 bit A/D converter is the heart of this outstanding performance.

IME Model 8080TR Universal Input Smart Transmitters are designed for use in process industries where vibration, inclement weather, and corrosive atmospheres prevail. The electronics are enclosed in a low copper epoxy coated Aluminum housing and for more aggressive environments, a SS316 housing is optionally available. The housings meet the requirements of NEMA 4X and IP67, and are also certified Explosion Proof by FM / CSA and ATEX (CENELEC).

The output current is temperature linearized and can be set to be 4 to 20 / 20 to 4mA or any range within these limits. The current is limited to 3.6 and 22mA. The unit updates are 3 times per second for the display and 4 times per second (max.) for the current output.

Exceptional digital accuracy of typical ±0.1oC is provided for all the sensors regardless of the calibrated span. Extremely accurate cold-junction temperature measurement provides precise compensation throughout the entire ambient range. The unit also accurately measures and compensates the RTD sensor leads into 3-wire connection.

The transmitter can be set and wired to perform differential measurement conversions of temperature sensors as well as mV sources.

The transmitter is fully configurable by connecting to a PC with no external power supply required. The configuration parameters are stored in a non volatile memory.

Digital output data can be obtained via a communication port located on the front panel. Continuous, average and max/min readings can be monitored.

Detection of sensor breakage or disconnection of input leads, forces the output to a pre-defined up/down scale value. The unit continuously monitors the sensor and automatically returns to normal operation mode when the sensor is recovered.

In applications where no local indication is required, the tempered glass cover is replaced by a solid cover and no LED indicator is provided.

The USTCAL configuration and calibration software is a PC-based software package. The PC is connected to the transmitter via MC232-communication cable, which contains the electronic interface circuitry. This feature makes the configuration process very easy, as it does not require the transmitter to be wired to an external power supply. The Windows based software conducts the user to the configuration steps in a friendly and simple interactive manner.

Both the Aluminum and the SS316 housing are certified NEMA 4X and IP67. IME Model 8088TR and ND can be optionally provided with certification and a SS Nameplate for use in Hazardous Area Applications.
