P6000A 物位仪器
6-Digit Frequency Meter, Tachometer, Rate Meter, Timer or Totaliser
In its base configuration, the P6000A is a microprocessor-based, 6-digit, 1/8 DIN counter which can be configured by front-panel keys or by a personal computer as a frequency meter/tachometer, frequency-ratio meter, period/period-average meter, time-interval/time-interval-average meter or totaliser. It combines these five operating modes with ease of setup, wide dynamic range, six-figure crystal-based accuracy, and software scaling. With the addition of an optional Analogue-to-frequency signal conditioner, the P6000A can become a software-scalable process meter with two setpoints and exceptionally wide zero offset capability. It can also become a 6-digit Analogue integrating totaliser. The P6000A provides a five-key front panel, which can be used to select mode of operation, scale factor, zero offset and two setpoints for ON/OFF control or alarm. Setup parameters can be saved in non-volatile memory with four levels of front-panel lockout for program security. In addition, the P6000A can be programmed via RS-232. It can also report its own setup data and transmit ongoing readings and alarm status via RS-232 or 20 mA ASCII current loop. The P6000A measures frequency or period by counting the number of 11.059 MHz clock pulses during an actual gate time t, which corresponds to an intergral number of signal periods N. This technique allows high-accuracy low-frequency measurements. Frequency is calculated from N/t, period from t/N. Operating Modes, Features and Options Operating Modes Frequency/tachometer from 10 -6 Hz to 7 MHz Frequency ratio FB/FA from 0.02 Hz to 7 MHz Totaliser up or down from 99,999 to 999,999 or accumulating stopwatch Period/period average from 140 ns to 36 days Time interval/time interval average/stopwatch Process meter for 4-20 mA, 0-2 or 0-10 V input Integrating totalizer for 4-20 mA, 0-2 V or 0-10 V input Fast Low-Frequency Measurement Every 50 ms + 1 signal period Slower read rates for frequency averaging Programming Options Scale factor from 99,999 to 999,999 (any decimal point, multiply or divide) Offset from 99,999 to 999,999 (any decimal point) HI and LO setpoints for control or alarm Programming via front-panel or RS-232 Program stored in non-volatile memory Four levels of program lockout for security Fixed decimal point or autoranging Input Signal Conditioning Options Dual-channel TTL with protection to 25 V Single-channel, isolated, with excitation Dual-channel, isolated, with excitation Single-channel, non-isolated, with excitation Analogue input, isolated, 4-20 mA, 0-2 V, 0-10 V Output Features & Options RS-232 or 20 mA serial ASCII output (std) Parallel BCD output, isolated (opt) HI, LO, GO 150 mA open-collectors (std) Dual 8A Form C relays (opt) Analogue output, isolated and scalable, 4-20 mA, 0-20 mA, 0-10 V (opt) Display & Mechanical Features Six 14 mm 7-segment LED characters Five-key programming front panel (std) Plain front panel (opt) Screw-clamp connectors for signal and power 1/8 DIN case (92 x 45 mm Panel Cut-Out) Please refer to the pdf data sheet for full specifications
