Typical Technical Parameters Parameter Specification Model Type CL6821 Input Signal 4-20 mA DC (Two-wire) Output Pressure 3-15 psig (0.2 - 1.0 bar) - This is the most common range for this model. Supply Air Pressure 20 psig (1.4 bar) minimum, 35 psig (2.4 bar) maximum (for 3-15 psig output) Air Consumption Very low (Quiescent: < 0.2 SCFH) Accuracy Typically ±0.5% of span Linearity & Hysteresis Typically ±0.5% of span Enclosure Rating General Purpose (Not weatherproof). For harsh environments, a separate enclosure was often used. Ambient Temperature -20° to 180°F (-29° to 82°C) Weight Approximately 1.5 lbs (0.7 kg) Mounting 2-hole bracket or directly to a NAMUR pad on an actuator.
