Pump Head, Flow and Water Power Measurement
Coupled with the appropriate pressure transducers and flow meters, Himmelstein’s Model 721+ will display the pump head (CH 1) in PSI, and/or flow (CH 2) in GPM and water horsepower (CH 3). Any of the three channels can be displayed by using front panel switches. Current and max/min data may be recalled for any or all channels and limits may be set on each channel. The limits can be downloaded from a host computer and test data can be uploaded to that computer.
Compressor Ripple Torque, Running Torque and Speed Tester
Our model 721+ with a torque sensor will check the single-phase motor and compressor combination to verify that ripple torque, running torque and speed are acceptable. Excessive ripple leads to noise and vibration, which reduce life. Running torque/speed checks verify efficiency.
This instrument measures torque (CH 1 and 3) and speed (CH 2). After reaching minimum acceptable running speed (detected by CH 2 low limit), Channel 1 is automatically switched to its Do Max/Min mode. Then, Channel 1 limits classify its spread or torque ripple. When the assembly is at final speed, CH 2 limits classify the running speed, and CH 3 limits classify running torque. The display is set to read ripple torque (CH 1) or running torque (CH 3) and running speed (CH 2). A Good/Bad signal is also generated.
