APPLICATIONS

TYPICAL

Model 961 single point switches may be used for high or

low level alarm, as well as for pump protection. The Model

962 dual point unit is typically configured to measure

high/low, high/high, or low/low levels.

The single point 961 can be mounted vertically or

horizontally in vessels, bridles, or pipes. The dual gap 962

is always top mounted.

A broad selection of transducer materials allow the 961/962

to be used in a wide variety of process media. Metallic

transducers include 316 SS, HastelloyÂ® C, and MonelÂ®. The

316 SS transducer has a NACE construction option for sour

gas service, and can also be built per ASME B31.1 and

B31.3 piping codes. Thermoplastic transducers include

KynarÂ® and CPVC. These corrosion resistant plastic trans-

ducers feature a stiffening tube that runs the length of the

transducer for extra rigidity. Kynar-faced 316 SS flange

options are offered with the Kynar transducers.

PUMP CONTROL

A DIP switch on the Model 962 allows it to be configured

to control level, or to function as a pump controller. In the

pump control mode the unit can perform auto fill or auto

empty of tanks, sumps, or wet wells. The tip sensitive

lower gap allows liquid levels to be pumped down to

within 1â4" from the bottom of the vessel. The rigidity of the

flow through upper gap allows the 962 to be used even

when sumps experience severe turbulence from vessel

fill lines.

HYGIENIC

The hygienic version of the Model 961 features a deep

drawn stainless steel electronics housing. Tri-ClampÂ® and

DN65 Varivent hygienic process connections are offered for

use in food & beverage, pharmaceutical, and biotechnology

applications. These hygienic transducers have 3-A

(Authorization #596), EHEDG certification (per TNO Report

# V4772/01) and a 20 Ra finish to provide a uniform and

ultra-smooth surface that inhibits microbial growth.

Electron beam welding technology is utilized to facilitate a

crevice-free surface inside the transducer tip. This allows

these transducers to be used in a wide variety of hygienic

applications where CIP (Clean-in-Place) is used to remove

any contamination from the transducer surface.
