Programmable Tachocount

4B Tachocount TACH3V5
Programmable Tachocount

The TACH3V5 Tacho is low cost electronic display which can be user programmed to indicate speed, distance or time intervals. The unit incorporates a 4 digit red LED display with programmable auto decimal point, in a DIN 96 x 48 enclosure (panel cut-out size: 92 x 44 mm). A relay output is provided for speed control use.

Speed Relay

速度继电器  AUE400 & SR4000
Speed Relay

The Speed Relay is used to monitor the speed of a rotating shaft and detect if it rises or falls below a preset safety level.

The DIN rail mounted speed relay can be used with any Rotech encoder, and with 4B’s WDA or P800 proximity sensors.  A user adjustable underspeed relay contact output can sound an alarm or shutdown machinery when the shaft speed falls below the preset level.

Hazard Monitoring Design Service

Hazard Monitoring Design Service

Preventative maintenance can help reduce the risk of equipment failure and consequent downtimes. When it comes to monitoring your bucket elevators and belt conveyors, 4B can recommend you the ideal combination of sensors and monitoring systems to suit your requirements and budget.

4B provides an extensive range of their own ATEX / IECEx / CSA approved hazard monitoring systems, misalignment switches and bearing temperature monitors and level controls. We can offer you anything from a replacement sensor to a fully integrated hazard monitoring system which can be operated either as a stand-alone system or connected to your PLC.

And if you do not want to install hazard monitoring sensors on every piece of equipment in your plant straightaway, we can offer you a scalable solution starting with carefully chosen equipment and systems that can be expanded at a later date to encompass other machines in the plant.

We can also offer you an installation service, and we do provide a competent after-sales technical service to help you overcome any technical problems with your monitoring equipment.

To get a recommendation from our engineers, please fill in the electronics questionnaire below. Please fill this form in as accurately as possible to allow us to deal with your enquiry more effectively.
