TMR-223
TML Pam E-3004A TML MULTI-RECORDER TMR -200 series NEW Carrier type Strain Unit TMR-223 Dynamic measurement resistive to noise This is a carrier wave type strain full bridge unit for TMR-200, which features excellent resistivity to electrical noise. It is most suited to on-site measurements where the influence of induction noise and/or commercial power supply noise are expected. Number of input channels is eight for one unit, and it is expandable up to 80 channels at maximum for one system. Since the unit is constructed small and available for multi-channel configuration, it is also suited to in-vehicle measurement. ● A carrier wave type bridge excitation resistive to noise ● Carrier wave frequency 5kHz ● 8 channles/1 unit ● Vibration-proof and small construction SYSTEM BLOCK DIAGRAM Advantage of carrier wave type bridge excitation ●Not affected by low frequency noise including thermoelectromotive force and commercial noise ●High SN ratio and superior stabilBridge Box Strain gauge based transducers Strain Strain Load Cell Acceleration Pressure gauge full bridge transducer transducer ity Measuring method of carrier type strain unit Strain generated Amplified Detected Final output Bridge excitation Detection Amplification Filter AC Bridge excitation Bridge excitation waveform（Example：5kHz） Specifications Carrier type Strain Unit Number of channels Gauge resistance Bridge excitation Measuring range TMR-223 8 120∼350Ω 0.5Vｒｍｓ、2Vｒｍｓ5kHz ±20000×10-6 strain (with 2Vdc bridge excitation) ±80000×10-6 strain (with 0.5Vdc bridge excitation) Measuring accuracy ±0.3%FS(at 23±５℃) Balancing method Software Initial balancing range Resistance ±10000×10-6 strain Capacity 3000pF Resolution 1×10-6 strain (with 2Vdc bridge excitation) 4×10-6 strain (with 0.5Vdc bridge excitation) Stability on zero ±0.1×10-6 strain/℃ Stability on span ±0.05％/℃ Frequency response DC∼2.5kHz Lowpass filter Digital filter Cutoff frequency 5Hz∼1kHz(settable every 1Hz) and PASS （2.5ｋHz）-3dB±1dB Cutoff characteristics 5Hz∼1kHz Butterworth filter, Bessel filter -48dB/oct PASS (2.5ｋHz) Butterworth filter -48dB/oct Highpass filter Digital filter Cutoff frequency 0.2Hz,1Hz, or OFF (-3dB±1dB) Cutoff characteristics -12dB/oct Power supply DC 10V∼30V 0.3A MAX Operating environment 0∼+50℃, less than 85%RH (no condensation） Anti-vibration 29.4m/s2 Dimensions 200(W)×25(H)×100(D) mm （excluding projecting parts） Weight 600g 【Standard accessories】 Operation manual ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・1 copy Control cable CR-6460・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・1 pc.
