KH - HZD integrated vibration transducer installed

KH - HZD integrated vibration transducer installation and maintenance, explain each step of the way is very detailed

integration vibration transducer is a kind of high integration, combined temperature sensor and vibration sensor, can simultaneously measure temperature and vibration, in turn the transmitter and sensor integration, temperature and vibration value output corresponding to the two wire system, 4 - 20 ma signal, can be directly on the PLC and DCS system, the product design is reasonable, simple structure, stable performance, easy to use, such as fan factory equipment fault monitoring zui optimal choice.

integration vibration transducer installation steps are as follows:

1. Location: vertical or horizontal installation on the measured vibration, will be at the bottom of the sensor M10 x 1. 5 x 10 screws on the shell being measured, then the sensor twist on it tight.

2。 Installation dimensions and specifications: see figure, if the transmitter installation location by the scour such as steam, to reduce the environmental temperature transmitter, the need to add protective measures, usually without protection.

3。 Connection details: brown wires connect DC24V power supply side, negative side blue wires connect DC24V power supply, and brown, and blue wire is 4 ~ 20 ma output pin. Wire requirements with good insulation performance, connecting the two core shielded cable.

integration vibration transducer is widely used in electric power, steel, petrochemical industry such as fan, water pump, compressor, turbine rotating machinery and other equipment such as vibration. Amount of various vibration equipment run time is an important indicator of measure equipment operation is normal, the application of vibration transducer vibration is an economic, scheme. All integrated vibration transducer series, according to the type selection can measure the casing vibration velocity and vibration displacement, the user can refer to selection guide to choose suitable for their own products.

integration of using and maintenance of vibration transducer

1) The machine shell ( Enclosure) Determine the installation position, demands on surface level off, as far as possible to open a thread hole will be subject to actual installation size, the transmitter clockwise to the corresponding thread hole, until fully tighten the screw thread, transmitter and machine at the bottom of the enclosure fit closely. If the machine does not have the appropriate installation plane, can be in the machine shell ( Enclosure) On welding or bolt installation has installed base of a certain intensity, install the transmitter on this base, it is suggested that the transmitter X ( Level) Y ( Vertical) The direction of the installation.

2) The selection of transmitter installation position, should try to request the location is enough big rotor vibration according to the facts to the bearing housing or casing. In addition, the physical installation of transmitter to be more careful. Incorrect installation can cause transmitter reduced amplitude and phase response, and can lead to do not represent the real machine vibration signal. It is strictly prohibited to transmitter system charged disassembling and connection; Terminals must be compact and firm, not loose; After check cables and wiring terminal contact good no short circuit, electricity. Confirm the working power supply should be + 24 VDC transmitter.

3) Integration of vibration transducer should not clash, keep clean; Should be based on the scene environment keep environmental protection processing of cable connection.

4) When the transmitter drift or use of the measured value is not stable, the processing method is as follows: check whether the connection parts fastening; Wiring is normal; Check whether the sensor is loose; Check whether sensors and transmitters of connection is loose, whether the shield at the transmitter end reliable grounding ( Signal ground) ； Check the transmitter to the DCS or recorder connection is loose, check whether shielding layer on the DCS side reliable grounding ( Protected area) Check around the sensor for heat source, such as gas seal leak, the sensor is beyond the working temperature range, lead to the output instability.
