Description

PREX3000 VECTOR INVOLUTE TYPE

 
PNEUMATIC FLOAT LIQUID LEVEL TRANSMITTERS  
MODEL: KQP  
   
        The PREX3000 instruments are pneumatic type transmitters which employ a combination of vector balance mechanism and involute mechanism.  
        The instruments are featured by high resistance against adverse environments, high turn-down ratio, high accuracy, and ease of maintenance.

Item Specification
(1) Elevation and suppression    (applicable to type 310 or 320)   (1) ElevationUse for an input range the low limit of which is higher than zero.
        SuppressionReverse of elevation. Used primarily for measurement of levels of low specific-gravity liquids.
  (2) Float weight adjustment mechanism.
        (applicable also to floats which are not of standard types)
        Use this mechanism to satisfy the following condition:
           WA – W = We                                     
           We: Elevation weight 1.2kg              W : Float weight                 WA: Basic weight for adjustment
  (3) Zero elevation mechanism (used for measuring range change by zero-point elevation)
        Use this mechanism to satisfy the following condition:
          Fe = πd2 / 4 * Le * p1.2kg                                           FeBuoyancy corresponding to amount of zero elevation (kg)          
          FR + Fe = πd2 / 4 * ( LR + Le ) * p1.6kg                     FRBuoyancy at measuring range (kg)
