QY type bridge deflection tester

Mainly used to measure the inclination angle, deflection value, inclination curve, deflection curve, and inclination differential value of bridges under static loading. Each set of this instrument includes4-8 QY inclinometers (quantity to be selected by the user), 1 junction box, and 1 set of bridge deflection analysis software.

941B ultra-low frequency vibrometer

It is a multifunctional instrument used for measuring ultra-low frequency or low-frequency vibrations. It is mainly used for pulsation measurement of ground and structures, industrial vibration measurement of general structures, ultra-low frequency large amplitude measurement and weak vibration measurement of high flexible structures. Each set of vibration meter includesSix 941B vibration pickups (four horizontally and two vertically) and one 941 amplifier (six wire). The 941 type vibration pickup adopts passive closed-loop servo technology to achieve good ultra-low frequency characteristics. The vibration pickup is equipped with four speeds: acceleration, low speed, medium speed, and high speed. An amplifier has the functions of amplification, integration, high steepness filtering, and impedance transformation. Users can select the corresponding gear of the micro toggle switch on the pickup and the parameter selection switch on the amplifier according to their needs, which can provide acceleration, velocity or displacement parameters of the measuring point, as well as different frequency bands and filtering steepness. This instrument has the characteristics of small size, light weight, easy use, high resolution, large dynamic range, and multi-purpose use. This instrument can be directly connected to various recorders and data acquisition systems.
