A 1959 Melville-Cornwall paper (8) described the use of their ratemeter
in cardiac applications, for measuring the interval between each heartbeat but providing an output calibrated in beats per minute.
The DPF80 Series (Dual Rate Totalizer) is a five-digit ratemeter
and a six-digit totalizer in a 1/8 DIN package.
Large, 40-bit deep counters complement a fast, 500 MHz counter/timer ratemeter
and digital/bar graph intelligent LCD.
Motor speed was measured with a magnetic pick-up mounted on the motor shaft and displayed on a Visi-tach digital ratemeter
. Light emission was monitored for 250 ms by ACE-MCS software operating with a channel dwell time of 5 ms.
Here the signal is the AC coupled via a blocking capacitor and passed on to pulse handling electronics such as the VG Quadrupoles SPC10 unit which combines a pre-amp, discriminator and ratemeter
in one unit.
"This is only the first step," responded Heiko Kunst (DG Climate), emphasising the Commission's desire to limit costs and administrative burdens for operators by proposing four methods based on current tools: bunker fuel delivery notes, or BDN, hold inspections, ratemeters
and direct measurement of emissions.
To detect dynamic charging during spectrum accumulation, it is useful to have within the EDS control software the capability to define a series of "ratemeters
" covering specified energy ranges that are placed throughout the x-ray spectrum (covering peaks and/or continuum windows), especially in the high photon energy range.
Key features and benefits of totalizers, predetermining count/controls, ratemeters
, timers, digital panel meters, flow totalizers and controls, temperature indicators/controls, special function controls, specialty products, and transducers and accessories are included.
