    產(chǎn)品描述
    The DPF6000 microprocessor-based, 6-digit 1/8 DIN panel instrument 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, reset stopwatch, and cumulative timer or totalizer/2-stage batch controller. However, the DPF6000 display cannot toggle between rate and total. Two frequency bs can be used to provide frequency ratio or time-interval measurements only; no other function of the meter can be perbed on two bs. The standard b of the DPF6100 is for two non-isolated TTL/CMOS-level signals with protection to 25 Vdc for use with amplified flowmeter bs. The DPF6200 provides a 20 Vdc output at up to 16 mA for direct connection to NPN or PNP open-collector or NAMUR sensors. A universal signal conditioner board in the DPF6300 and DPF6400 provides sensor excitation plus low level ac signal amplification, coupling, signal isolation to 350 Vp, and jumper-selectable low-pass filtering, debounce time, and hysteresis. AC sensitivity is +10 mV below 1 kHz. The DPF6300 and DPF6400 can be tied directly to low-level passive magnetic pickups (such as turbine and paddlewheel flow sensors), line voltages up to 240 V rms, and NPN, PNP, NAMUR, or contact-closure sensors. The DPF6300 provides signal conditioning on one channel, while the second channel accepts TTL/CMOS b. The DPF6400 provides signal conditioning on both channels. The DPF-6500 accepts 4-20 mA, 0-10, 0-5, or 0-2 Vdc bs for totalization/batch control or rate indication with alarms. Five Operating Modes In the frequency meter, the minimum display update rate is equal to 1 period of the frequency b. Thus, very low frequency measurements mean long update times (the unit could be made to wait up to 36 days before registering zero flow, for example). This must be taken into account when using the DPF6000 for very low frequency measurement. The DPF6000 can be set up as frequency-ratio meter, ideal for monitoring flow ratios. The DPF6000 can be set up as an up or down totalizer/2-stage batch controller at rates up to 7 MHz. The display capacity is -99,999 to 999,999 counts, with exponential bat up to 9.99 E9. Upon ac power loss, the latest reading is automatically saved in non-volatile RAM and is restored upon return of power.
