Bulk Modulus Cells
-
200,000 PSI Service
-
Metric units to 14,000 BAR or 14,000 Kg/cm2
-
10-point secondary standard calibration traceable to NIST
-
10-point primary standard calibration is available
-
Cells are available for both polar and non-polar fluids
-
Digital panel meters for pressure indication
and/or control
For hazardous location where pneumatic control is the only viable option,
Harwood offers the Bulk Modulus Cell, which provides a 3-15 psi output
signal proportional to process pressure. A 20 psi supply is required.

Standard readout device is a 6" receiver gauges which provides direct pressure
reading in KPSI. Part#:A-14942
-
Optional instruments such as 12" circular chart recorders and controllers
are also available. Please consult a sales engineer.
-
In applications where low level DC power (10 Volts) is acceptable, but
controls are pneumatic, improved measurement accuracy may be realized by
combining strain gaged transducers/readouts with I to P converters for
pneumatic control. Please consult a sales engineer.
