Distribution Box for Temperature

Measuring System, 10 Sockets RJ12

DescriptionDescription

Typical areas of application

• Monitoring of frozen goods as per

cold storage regulations

• Building instrumentation

• air conditioning systems

• Quality assurance

• Science and research laboratories

• Industrial temperature logging

Characteristic features

• Plug-in type distribution box

for DS1820 temperature probes

• 10 Sockets RJ12 usable for up to

8 or 9 Temperature sensors

• Integrated pullup resistor and

decoupling capacitor

• Ready made, in plastic housing

• inclusive of 4-core connection cable (1 m)

with both side plug RJ12 (6P4)

Available probes

The reasonably priced probes with PVC connection cable are meant

for measurement in open atmosphere, on surfaces or in non-aggres-

sive gas medium. The probes are sealed and can bear water contact

for some time. However, long term immersion in liquid is not recom-

mended.

The models with stainless steel probe tube are chemically stable and

the tube portion of probe can be submerged in liquid, the stainless

steel (1.4571) does not get affected. However, in the cable termination

area, the probe should not come into constant contact with liquid.

For application in pipeline system, pressure resistant models with 1/8“

or M10 threads are also available. These models with gasket are sui-

table up to 20 bar.

Further customised models can be manufactured for special applica-

tions. Please send your enquiry to us!

Formation of temperature sensor Networks

All necessary components, with plug-in type RJ12 connectors, are

available for the 16 channel temperature measuring system so that a

fully functional system can be developed even without soldering know-

ledge.

The speciality about wiring of the sensors is the „Bus technology“: All

sensors can be driven parallel on a 3-wire line over which both supply

and data communication can run through.

Hence, the bus topology is completely arbitrary: it can built both as a

star or extended structure. Mixed forms are also possible. It is only to

be ensured that the sum of all connection cables does not exceed the

maximum allowable length of approx. 60 m.

DATA SHEET Distribution Box for Temperature Measuring System, 10 Sockets RJ12 Hub Installing and configuration For connection of multiple probes, a hub is available with 10 ports (RJ12). One port is used for connection of temperature logger, and if necessary, another port is used for connection of another hub. As a result, 8 to 9 ports are available for connection of temperature probes. The hub has a supply capacitor and a pullup resistance of 10 kΩ for compensation of connection capacitance.

DATA SHEET Distribution Box for Temperature Measuring System, 10 Sockets RJ12 Thermal transition resistance of measuring object-sensor This is the main measuring error which occurs during surface measurements. This can be eliminated by providing good thermal contact through mounting in a tube, applying thermal conducting paste or thermal conducting adhesive.
