Robertshaw Capacitance Level Probes
The Robershaw Capacitance Level products
can be used to measure the level of liquids and solids in a variety of tanks, bins, totes etc.
Robertshaw has a number of probes to use with their Control Units
The capacitance probes are normally made of SS and may be coated with PTFE for conductive liquids and sanitary applications.
The 740A/C-A (bare) or 740A/C-B (Teflon insulated) is a medium pressure,
general purpose, rigid probe for level measurement involving liquids or dry
The 729A flexible probe is a general purpose probe designed for use in
applications where non-rigid probes are neither required or desired.
The 750 is an economical, low pressure, general purpose,
rigid probe for level measurement involving liquids or dry materials.
The 728B capacitance probe is designed for heavy duty service wherever a rugged probe is required.
The 738A ceramic-insulated, rigid probe is designed for use with Robertshaw
capacitance-type level and bulk measuring instruments. It is offered for use
in special and corrosive material measurement applications involving high
temperature and pressure conditions.
(rigid) or 150KB284 (flexible) bare, non-insulated probes are for extremely
high pressure/temperature applications. The flexible probe is designed for
use where long probe lengths are required.
The 741A/C is a general purpose, high gain, rigid probe for use with lower dielectric materials or where increased sensitivity/gain is needed.
The 727A high pressure, high temperature, “shortstop” probe is designed for use in
applications where product build-up or conductive coatings typically cause
erroneous control actions.
The 732A “shortstop” probe is designed for those tricky and difficult applications
where conductive coatings or product build-up typically cause erroneous
The 739B sanitary, flanged probes are for use in applications where ease of cleaning and/or
removal are a requirement.
The 736B probe is
available in both a general and heavy duty design, each with a Teflon-faced
flange for highly corrosive applications.
The 702A rigid
probe allows installation of a bent probe in cases where internal vessel
obstacles would otherwise interfere and prevent the use of a standard
one-piece gland probe.
