The MI3 is a rugged, IP65-rated miniature sensing head that can be placed in harsh environments inaccessible to conventional sensors. The MI3 is not a stand-alone sensor and must be purchased in conjunction with MI3MCOMM communication box to function.

Must purchase the RAYMI3COMM in order for the instrument to function.
Low temperature sensor with a measurement range of -40 to 600°C (-40 to 1112°F) and a fast response (<130 ms), provides an impressive array of solutions for your process needs. The miniature stainless steel sensing head is small enough to fit in many places that are inaccessible to conventional sensors and rugged enough to ensure reliable long term performance in the harshest industrial environments; it can survive ambient temperatures of 14 to 248°F (-10 to 120°C) without cooling. Although the MI3 sensor is small in size, it has all the performance you need– with 1% accuracy and a choice of high resolution optics up to 10:1.

Optical Resolution | 10:1 Distance : Spot size |
Ambient Temperature | 120ºC (248ºF) maximum |
Environmental Rating | IP 65 (NEMA-4) |
Construction | Stainless steel |
Cable Material | PUR halogen free, flame retardant insulation |
The Mi3 uses a digital I2C bus for communication between the sensing head and communication box. Care must be taken with respect to grounding and shielding.
To ensure reliable operation please only use a single point to connect to EARTH ground. In case of multiple heads it is advised to electrically isolate all heads using an air purge collar or isolated bracket.
There are 3 basic types of sensing heads. They are automatically recognised by the ‘COMM box and identified by their serial number. When installing multiple heads please make a note of the serial number stamped on the head itself and location. The head number can be modified by the front panel of the sensor.
If necessary fit the purge collar. This only applies to the Mi3 LT and G5, Mi3LTH will have the air purge collar installed during manufacture. For the Mi3100, the air purge collar can be installed at any time.
There are 2 basic versions of the communication box. ‘COMM(metal) and ‘MCOMM (plastic). There is also a ‘CONN box for connection up to 8 heads.
For the sensing head, shielded 4-wire cable is used for power supply and communication. To avoid inaccurate measurement and communication, the cable shield should be connected to the housing or shield connection of the COMM box. The sensor cable may be shortened, if necessary, but keep a minimal length of 20 cm (7.9 in).
The total head to box cable length affects the overall cable capacitance. The Mi3COMM (metal box) has a single I2C bus and can accommodate a total cable length of 30m.The Mi3MCOMM has a dual I2C bus and can accommodate 60m but installed as 2 x 30m, see example c. Intermediate connectors may be used with consideration to minimise capacitance. The overall cable length may need to be reduced.
The Mi3 head cable is shielded and must connect with the ‘COMM box housing or the ‘MCOMM box shield terminal.
Any input/output cables should be shielded. The output cable shield will be terminated at the cabinet, plc, psu end only if all other parts of the the Mi3 are isolated from EARTH ground.
The head number can be changed in the SN entry. In case the display is locked – press PAGE and ENTER simultaneously for 3s or until the padlock icon disappears. mA is only available on OUT2. OUT2 Source needs to be changed to the head number and OUT2 Value should be set to Tobject.
