产品描述
The OM-SL is no longer available please consult our Data Acquisition department for possible alternatives.
The OM-SL Series consists of
single-channel, portable low-cost
NOMAD dataloggers that require no
user setup. These dataloggers have
the ability to automatically adjust
both scale range and sample rate to
optimize the recording session.
OM-SL Series dataloggers operate
in three modes: Record, Standby
and Off. A red LED indicates the
mode of operation. In the RECORD
mode, the datalogger stores
information; in the STANDBY mode,
it retains the recorded information
for transfer to a computer; in the
OFF mode, the memory is cleared.
However, if the datalogger is turned
off by mistake, the cleared data can
be easily recovered.
The unique method of scale autoranging employed by OM-SL Series dataloggers provides you with the
best possible resolution for the recording session. Datalogging always starts with the highest
resolution and lowest scale range. The overall scale is divided into four ranges: 0-12.5% of full scale, 0-25%
of full scale, 0-50% of full scale, and 0-100% of full scale. Whenever a recorded value crosses over to a
higher scale range, the datalogger increases its scale range by a factor of two and repeats the reading.
There are 250 steps in each scale range. Resolution can be calculated by dividing the scale range in use by
250. To permit the host computer to interpret the data correctly, the datalogger notes, during the
recording process, when each change of scale takes place. Maximum resolution occurs when all
the recorded samples stay within the lowest scale range.
OM-SL Series dataloggers employ time extension recording which is an automatic process that updates the
sample rate and number of stored data points based on the length of the recording. The maximum
number of data points is 8192. When a datalogger starts a new recording session, it does so at its
fastest sample rate of 4096 points per hour (0.88 seconds per point).
The datalogger can record at this rate for two hours. If the recording
session continues beyond two hours, the time extension recording
technique becomes active.
Beginning with the sample, after the completion of two hours of recording, the datalogger continues
recording by selectively overwriting previously stored data. The datalogger also halves its sample
rate to 2048/hr (1.76 seconds per point) for the new stored values to be compatible with the previously
recorded values. Recording continues for the next two hours at this new rate until the remaining
4096 storage points are filled. The time extension recording process of selectively overwriting previously
stored data and halving the sample rate for new stored data continues every time the memory fills up. Like
the automatic scaling feature, time extension recording is practically
invisible to the user.
These dataloggers are the easiest tools to use to record data on-site and graph and analyze the data is
included. Models are available to measure temperature, DC voltage, DC current, AC voltage and AC
current. A clamp-on model for AC current measurement (OM-SL-CL600) is also available.
RMS Current Input Models OM-SL-L100, OM-SL-L110
RMS current input dataloggers support current probes with voltage (OM-SL-L100) or current
(OM-SL-L110) outputs. These dataloggers are ideal for many applications, including machine load
monitoring, load profiling and fault finding.
RMS Voltage Input Models OM-SL-L205, OM-SL-L230, OM-SL-L260
RMS voltage input models are
available for either 0 to 25 Vac
(OM-SL-L205), 0 to 300 Vac
(OM-SL-L230), or 0 to 600 Vac
(OM-SL-L260) input.
Typical applications include HVAC
troubleshooting, line voltage
monitoring, surge/sag monitoring,
and stray voltage monitoring.
4 to 20 mA DC Current Input Model OM-SL-L320
Monitor and troubleshoot your 4 to 20 mA process loops using this DC current input model. The current
loop can represent temperature, pressure, flow or any other process parameter. Scale and units are
programmable in software.
DC Voltage Input Models OM-SL-L410, OM-SL-L430
DC voltage input models can be used for many applications, including circuit design testing,
battery testing, and monitoring process transducers. Models are available for 0 to100 mV
(OM-SL-L410) or 0 to10 V (OM-SL-L430) input ranges. Scale and units are programmable
in software.
Thermistor Input Model OM-SL-L605
If you need to monitor ambient temperature in a computer room, food storage area, refrigerated
freight compartment, or in a process, consider this thermistor input model. The OM-SL-L605
measures temperatures via an internal or external thermistor.
Thermocouple Input Models OM-SL-L610, OM-SL-L620, OM-SL-L630
Thermocouple input models are the perfect solution for process temperature monitoring applications.
Any type J (OM-SL-L610), type K (OM-SL-L620), or type T (OM-SL-L630) thermocouple can
be connected via convenient colorcoded subminiature thermocouple input jacks.
