M-60 SERIES FIXED SET POINT FLOW SWITCHES Fixed Set Point Piston Flow Switches with Inline Flow

Available in 1/4" port size, the Malema M-60 Series Fixed Set Point Flow Switch is available in a wide range of construction materials including - acrylic, aluminum, PP, PTFE, PVC and stainless steel. These fixed set point flow switches monitor increasing and decreasing flow, with a flow range for water ranging from 750 to 1,600 CCM and 25 to 55 SLPM for air, these inline flow switches can be used in almost any application. When triggered, the M-60 Flow Switch will be within 10% of the desired set point, with repeatability of 5%.

M-60 Series Flow Switches have configurations available for single-pole, single-throw (SPST) or single-pole, dual-throw (SPDT) allowing for flexibility with different outputs for both the high and low set point. All Malema Fixed Set Point Flow Switches can have their own customized set points calibrated at the factory before shipping. Additionally, Malema offers pre-calibrated set point ranges for applications that do not require a custom calibrated range.

Features

  • Well suited for corrosive and non-corrosive gases or liquids
  • UL recognized for hazardous locations
  • Cenelec certified for intrinsic safety and encapsulation
  • Community Europe compliant
  • Universal mounting available
  • Extremely high level of accuracy within 10% of the desired set point for fixed set point models, and repeatability of 5% for all models of Malema Flow Switches.
  • Female NPT standard on flow switches providing small, compact design.
  • All Malema Fixed Set Point Flow Switches can have their own customized set points calibrated at the factory before shipping.
