Continuous Level Indicator RCL Series

This level continuous indicator utilizes hermetically sealed strain sensors to monitor level of product in storage silos, hoppers, and bins.


  • Precision electronic strain sensing with hermetically-sealed stainless steel strain sensor (U.S. patent no. 4530245)
  • Sensor mounted externally to the bin, which eliminates contamination or corrosion that can result from contact with the monitored product
  • Incorporation of the sensor as an integral part of the support member cancels temperature effects common to so-called “bolt-on” sensors, eliminating the need for protective insulation
  • Accurate to within ±2%
  • CL-100 Control
  • Enclosure Polystyrene plastic; IP-64 weather-tight
  • Temperature Range -10°C to +50°C; Temperatures down to -40°C will not damage unit
  • Power Requirements Less than 10 W; 120/240 VAC selectable; -15% to +10%; 48-62 Hz
  • Outputs Three (3) SPDT dry contacts rated 5 A at 250 VAC (low, high, overflow)
  • Optional 4-20 mA output proportional to level indication
  • Display 50-segment LED bar graph changes in 2% increments


  • Digital C-Level Control
  • Enclosure DCL-100 Panel Mount: DIN standard 144 x 72 mm, front panel IP-54
  • DCLF-100 Field Mount: Polycarbonate IP-65 (NEMA-4X)
  • Temperature Range Operating Temperature: 0°C to +40°C; Storage Temperature: -20°C to +70°C
  • Power Requirements 110/220 VAC selectable; -15% to +10%; 48-62 Hz
  • Outputs Four (4) SPDT; NO dry contacts rated 0.5 A at 240 VAC; Optional 0-20 mA, 4-20 mA, 20-0 mA or 20-4 mA;
  • Optional RS-485 serial communication
  • Display LCD with backlighting; 8mm height; 16-digit alphanumeric
