Description:

The Rosemount Analytical models 389 and 389VP are insertion style pH/ORP sensors with integral preamp. These sensors are compatible with nearly all Rosemount Analytical pH/ORP analyzers. Both models are combination sensors (pH, reference, and temperature within sensor body) and measure pH or ORP (Oxidation/Reduction Potential) of aqueous solutions in pipelines, open tanks, or ponds. Models 389 and 389VP are suitable for virtually all applications and are compatible with Rosemount Analytical and other manufacturers' instruments.

The Rosemount Analytical models 389 and 389VP are housed in a molded Tefzel body with Viton o-rings, making each sensor virtually indestructible and chemically resistant. The simplified construction, designed with user convenience in mind does not require electrolyte replenishment or any high maintenance troubleshooting procedures. The 389 features an integral cable design while the 389VP is offered with a watertight Variopol VP multiple pin sensor-to-cable connector which eliminates re-wiring and cable twisting when replacing sensors. Installation is easily achieved through the wide variety of mounting configurations. Both Models feature 1 inch (MNPT) front and rear facing connections for insertion, submersion, or flow-through pH and ORP applications.

Both the 389 and 389VP are provided with a triple junction reference which protects the reference element from harsh elements and helps prolong the sensor life. Both the 389 and 389VP require a preamplifier to convert the high impedance pH signal into a stable, noise-free signal. The 389 offers the choice of an integral sensor preamplifier. Both models can use a remote preamplifier, integral to the analyzer/ transmitter or in a remote junction box. All preamplifiers have a transmission capability of up to three miles.

Applications:

Rosemount Analytical 389 and 389VP ORP and pH sensors are insertion style sensors with integral preamp. Both models are combination sensors (pH, reference, and temperature within sensor body) and are used for the measurement of pH or ORP (Oxidation/Reduction Potential). Both the 389 and 389VP are compatible with Rosemount Analytical and other manufacturers' instruments.

The 389 family of sensors are extremely durable and offer a watertight Variopol (VP) option for quick replacement and prevents cable twisting. A triple junction reference protects the reference element from harsh elements and helps prolong the sensor life. A choice of hemi bulb or high pH glass electrodes is available to best meet various application needs.

Installation is easily achieved through the wide variety of mounting configurations. Both the 389 and 389VP ORP and pH sensors feature 1" (MNPT) front and rear facing connections for insertion, submersion, or flow-through ORP and pH applications.
