Eliminating Dispensing Contamination
A low-level sensing reservoir system from Dymax Corp. prevents empty material reservoirs from introducing air into dispensing lines, thereby eliminating contamination during the dispensing
process. The company, which develops oligomer, adhesive, coating, dispensing and light-curing systems for applications in a wide
range of markets, said its system utilizes an adjustable sensor for
use with pressurized reservoirs and features an SB-100 controller that activates a warning when the material in the reservoir
reaches a specified low level.
The controller also has an external PLC connection that allows
for a total line shutdown, saving time and money by stopping the
dispense system when material reservoirs are empty, Dymax said. The sensor configura-
tion is adjustable, allowing operators to set specific levels of material to signal warning
and automatic shutoff options. The low-level functions include remote visual beacon,
audio buzzer and auto shutdown. There are no wetted components — the sensor does
not contact fluids, so it’s compatible with a wide range of materials, the company said.
Subminiature Pressure Switch
Gems Sensors & Controls of Plainville,
Conn., has developed a subminiature
pressure switch designed for medium- to
high-pressure monitoring within space-constrained applications.
The Model PS61P OEM subminiature
pressure switch incorporates a hardened
alloy-steel piston actuator designed for
expanded overpressure performance.
The low-mass unit occupies a 0.94 in.
diameter hex footprint and measures
less than 2 in. The switch is designed to
reliably monitor standard pressures from
510 to 4350 psi, with an enhanced burst
pressure rating of 22,000 psi.
The Model PS61P is designed for
higher-pressure, cyclic-pressure and
pressure-spike environments. In addition, its size-to-performance ratio is suited for demanding off-highway vehicle,
agricultural and construction equipment
applications, particularly where space
constraints and performance limitations
have traditionally otherwise excluded
OEM pressure switch specification, the
Gems said the Model PS61P is highly
configurable off the shelf with choices
of alternate seals, fittings and electrical
terminations to meet unique OEM, aftermarket and retrofit requirements.
Option For Connectors
Ladd Distribution has
released TE Connectivity’s
Deutsch HDP20 Series wide-threaded adaptor with the L024
modification and backshells.
The HDP20 Series connectors
fitted with the L024 modification
work with TE’s new and wider Deutsch screw-on ruggedized thermoplastic backshell and
are part of TE Connectivity’s Industrial & Commercial Transportation product portfolio.
When compared to other backshell styles, Ladd said the new L024 modification and
wider backshells significantly increase the serviceability of the connectors by providing
easier access to the rear grommet, making contact insertion and removal easy.
The L024 modification and backshells are available for size 24 or 18 HDP20 con-
nector shells and are engineered to provide an increased level of protection from harsh
conditions, provide strain relief and improve aesthetics for a professional finished look,
the company said.
Marsh Bellofram Corp. has introduced its Type T289
industrial gas backpressure regulator. The company said its
Type T289 offers dual functionality as both a backpressure
regulator and high-flow relief valve with an adjustable set
point, making it particularly effective in the monitoring of air,
nitrogen, natural gas, propane and other industrial gases.
The compact size of the Marsh Bellofram Type T289 allows
it to be used in place of a standard relief valve for protection
against over pressurization in the downstream system, the
company said. With its large diaphragm area and integral
pitot tube booster, the regulator can offer quick and smooth response to excessive pres-
sure relief requirements, particularly within low-pressure settings, Marsh Bellofram said.
The Type T289 design allows for consistent high-reliability performance with high flow
rates, throttling-type relief and tight shutoff. Optional regulator rebuild kits are also available.
