Differential pressure gauge
DCT/Sensotec Inc.,
Columbus, Ohio |
 The
Model JG in-process wet/ wet differential pressure gauge incorporates a
high-accuracy transducer and an enhanced-resolution four-digit display; accuracy
is 0.2 percent over ranges from 1 to 10,000 psid. The device may be battery
powered, or it can operate on 110 ac or 11-32 V dc. It uses tactile feedback
raised membrane buttons to control on/off, zero, and tare, and to allow access
to both high- and low-pressure readings, updated three times per second.
The units are manufactured from stainless steel, use strain gauge technology,
and have no moving parts; 1/4-18 NPT male pressure ports are standard. The
manufacturer claims consistent performance, excellent overpressure tolerance,
and minimal calibration and maintenance requirements. Multiple units of measure
are field selectable. The device is built to withstand harsh industrial
applications. It has a NEMA 2 rating and an operating temperature from 30¼
to 160¼F; NEMA 4 is optional, with temperature rating of 0¼ to
180¼F.

Threadless
pressure regulator
Parker Hannifin Corp.,
Richmond, Calif. |
The company's Veriflo Division's IR4000 Series
internally threadless pressure regulator for industrial and analytical
applications uses a unique compression member rather than traditional internal
threads. The compression member secures a poppet in place without the particulate
generation and entrapment of threaded designs. In addition, the IR4000 also
has a dual screen filter with a 100-micron wire mesh and a 10-micron sintered
metal element as a barrier against contamination.

Sandwich
mounts
E-A-R Specialty Composites,
Indianapolis, Ind. |
This firm's standard Isoloss urethane elastomer
sandwich mounts are designed to provide high-performance shock protection,
vibration isolation, and noise control in a wide range of OEM equipment
applications. The mounts feature cure-bonded metal fasteners that limit the
need for additional assembly hardware, and are available in 20 standard sizes,
in diameters from 3/8 in. to 1 1/2 in., for loads from 1/2 lb. to 250 lbs.
per isolator. Mounts are available in two proprietary formulations: Isoloss
HD urethanes are exceptionally strong and exhibit high damping and uniform
modulus throughout a broad temperature range; Isoloss VL urethanes are durable
with low modulus, and provide good damping and stable material properties
in widely varying temperatures. Both are said by the manufacturer to combine
high damping performance and mechanical strength with excellent environmental
resistance properties, and to require a minimum of sway space to deliver
a desired level of shock protection. According to the company, these mounts,
unlike mounting systems incorporating materials such as neoprene or natural
rubber, effectively absorb mechanical energy, limit deflections and stresses,
and dissipate the energy as low-grade heat.

abrasives. The belt can be changed in one minute or less. No coolant is required
in most applications. The headstock-tailstock arrangement simplifies the
load-unload operations because chucks are not required.

the label's life. Because the data can be updated, there is no need to relabel
a pallet or other container each time it is redirected or its contents change.
Smart labels are read using radio waves, which means information can be
