COMPLETE INTRINSIC SAFE SENSOR SYSTEM:
Junction Box - Sensors - Transmitters
Resistance Thermometer - Type MNS
- Tank Thermometer
The stainless steel, (AISI 316) conical interface type FCR is the interface between almost any flange size and the Rosemount
2240S temperature transmitter designed as the connection to the MNS resistance thermometers.
Mineral insulated thermometer for temperature measurement in insulation and
concrete surroundings e.g. liquid gas tanks and LNG tanks (coiled diameter min.
1 m).
Measuring temp. range: -200°C to +100°C.
The measuring element is glass encapsulated platinum elements according to
EN60751.
Protective sheath of AISI 316L filled with compressed MgO powder. Sensor tip
Ø6 AISI 316L.
Response time (mean values) measured at velocities in:
water w. 0.4 m/s:
0.5 = 6.4 sec. - 0.9 = 27 sec.
Recommended measuring current: 1 mA (max. 2 mA).
Approvals: Ex ia IIC T6 Ga
Options include thermometers up 250 m in length, calibrated sensors certificates supplied with the Van-Dusen coefficients allowing overall system tolerances better than +/- 0,124 degree C within a temperature range of -195 degree C to -100 degree C.
The 2240S can connect up to 16 (or 8 duplex) 4 wire resistance thermometers.
Note:
Sensors need to be with minimum
450 mm lead wire.
Only 8 duplex sensors can be connected
in the transmitter.

To achieve high accuracy we recommend the 4 wire calibrated version.
Each calibrated sensor is supplied with a certificate stating its own individual coefficients
Ro, A, B and C to substitute the standard coefficients in the EN60751 platinum curve.
By use of the coefficients the uncertainty of the sensor will be <=20 mK in the range -195
to 100 °C.The transmitter will represent the major part of the total system uncertainty.
