More about loggers and recorders...

The new Tiny USB stick loggers are so low priced, and have such a versatile range, you can almost log any signal with them. However they log quite slowly and this may be an issue.

Fast loggers have a bigger price tag and are more sophisicated large memories, large IO, Networking, Wireless, Displays and more.

Another type of logger is the wireless logger, that collects signals from multiple points at the same time using Wireless technology.

The most versatile logger is the Laptop with a DAQ card or a USB DAQ module. Most vendors now supply free logger software for their DAQ hardware.

AC & DC Power loggers have a built in circuit for managing AC and DC high voltage and currents. Most AC power loggers give Volts, current, watts PF, KwHr and many other parameters.

MasTec has both paperless recorders with LCD displays and older style paper recorders.

Signal Conditioning

A signal conditioner is a device that converts one type of electronic signal into a another type of signal. Its primary use is to convert a signal that may be difficult to read by conventional instrumentation into a more easily read format.

Signal Conditioners are typically linked to transducers - Strain Gauge, Thermocouple, RTD, Thermistor, Silicon Temp, 4-20mA, mV, V, Potentiometer, Quadrature Encoders, Absolute Encoders, Frequency, Filters etc

When a signal is amplified, the overall magnitude of the signal is increased. Converting a 0-10mV signal to a 0 -10V signal is an example of amplification.

Electrical Isolation
Electrical isolation breaks the galvanic path between the input and output signal. That is, there is no physical wiring between the input and output. The input is normally tranferred to the output by converting it to an optical or magnetic signal then it is reconstructed on the output. By breaking the galvanic path between input and output, unwanted signals on the input line are prevented from passing through to the output. Isolation is required when a measurement must be made on a surface with a voltage potential far above ground. Isolation is also used to prevent ground loops.

Converting a non-linear input signal to a linear output signal. This is common for thermocouple signals.

Cold Junction Compensation
Used for thermocouples. The thermocouple signal is adjusted for fluctuations in room temperature.

Many sensors require some form of excitation for them to operate. Strain gages and RTDs are two common examples.

Some Signal Conditioners convert voltage to frequency and then gated counters are used to capture the data, as in OPTO 22 systems.

Most Signal Conditioners are analog in and analog out with conversions, say millivolts in and 4-20mA out or RTD in and +/-5volt out etc.

If you also are looking for signal conditioners with high common mode rejection ratios and excellent normal mode ratios ++ 1500VAC RMS Galvanic isolation, Dataforth makes these.

Dataforth is a worldwide leader in the design and manufacture of signal conditioning and data communications products for industrial and institutional markets.

Inverter Chargers

An inverter/charger is a combination of an inverter, battery charger and transfer switch into one complete system. When AC power is available, the inverter/charger recharges the batteries.

MasTec Ltd has a full range of Inverter Chargers, and stocks many models for the Marine, Mobile, Automotive and Industrial industries.

For mobile power, marine power, Home Power we recommend a transformer based Inverter charger, as in most cases these devices will be connected to inductive loads.
