Endress+Hauser Soliphant FTM50-ATD2A4A32AA

Limit switch

Endress+Hauser Soliphant M universal vibrating point level switch is used for fine-grained bulk solids or powders with low bulk density.
FTM50 sensor is made in a compact dust-proof and explosion-proof design, it can be mounted in any position.
Common uses: sugar, feed, grain, flour, milk, cocoa powder, chalk, washing powder, sand, cement, gypsum, granules. plastic.

The main advantages of the FTM50 level transmitter include:

• no calibration required: simple installation ("on and );
• no moving parts, resp. no wear and tear. service life;
• not sensitive to external vibrations and sticking of the product: does not require maintenance. and does not depend on the composition of the product;
• convenient and easy to read values ??on the display in the cap of the sensor;
• density adjustment or response delay;
• short fork (L-100 mm);
• build-up/wear indication.

Technical data:

• Measurement principle: piezoelectric conversion in a tuning fork
• Mat. sensor: 316L (3.2 mkm - PTFE coating, ETFE coating - 0.8 mkm)
• Measuring systems:
  - off. limit level (FEM 51,52,54)
  - level sensor (FEM 55,57,58)
• Connecting cables:
   -electronic inserts: cross-section no more than 2.5 mm2; case according to DIN 46228
   - protective grounding of the case: cross-section no more than 2.5 mm2
   - equipotential connection of the case: cross-section no more than 4 mm2
• Cable connector: feature of the case; Phoenix terminal block on electronic insert

Input signals:

• Measurement value: level (depending on mounting location and overall length)
• Measuring range (triggering): total length 200/145 mm (possible variants : Standard fork 155 mm long (≥ 10 g/l); short fork 100 mm (≥ 50 g/l))
•  Input signal:
   -coated plates = low amplitude oscillation
   - uncoated plates = large amplitude of oscillation
• Frequency of oscillation:
   - standard fork: ~ 140 Hz
   - short fork: ~ 350 Hz

Output signals:

• Galvanic isolation: FEM54 – between sensor and power supply
• Switch mode: binary
• On mode power supply: the output is set to "alarm" and no later than 3 s it switches to normal. out. signal
• Trip delay: 0.5 s – the sensor is covered with the working medium; 1.5 with – the sensor is not covered by the medium (1 s for a short plug)
• Explosion protection: FEM54 – for operation in explosive gas-air atmosphere: Ex d Ex de, XP, intrinsically safe sensor circuit Ex ia, IS; for dust-air atmosphere: Dust-Ex, DIP
• Operating temperature: -50°+280°C
• Pressure: -1°+25 bar
