Standard Sensors - Data Logging Systems by Logic Beach, Inc

To assist our customers with the completion of the data acquisition system that meets their specific requirements, Logic Beach sources, qualifies and resells a variety of sensors and transducers from reputable companies. We offer these commonly deployed sensors as a convenience to our customers and because we know they work with our instruments.

Many of our customers come across applications where running wires between the data acquisition instrument and the sensor is difficult or expensive. As a solution to this problem, we now offer a suite of wireless transducer interfaces. Thermocouples, RTD,s, counts, events, 4-20mA, Vdc, etc are all supported.

Keep in mind that the following devices are but a partial offering of transducers that can readily be connected to our data acquisition instruments. Feel free to email or call Logic Beach for assistance in selection of compatible sensing devices for your application requirements.

Sensors	Sensed Property	Transducer Output Signal	Transducer / Sensor Offering Overview
	Temperature (Thermocouple)	mVdc per TC Curve	Thermocouple probes; various types, wire gauges and probe configurations.
	Temperature (Thermistor)	ohms per NTC Curve	Thermistor (NTC resistive) probes
	Humidity	Vdc	Relative humidity and humidity combined with temperature probes
	Pressure	4-20mA Vdc	Standard stainless steel pressure transducers; full offering of pressure ranges and common outputs and fitting types
	DC Current	4-20mA Vdc / mVdc	Various DC current transducers with full scale ranges up to 600Adc
	AC Current	4-20mA Vdc / mVdc	Various AC current transducers with full scale output ranges up to 2400Aac
	AC Current Threshold Switches	Switched (SSR)	Current threshold sensing transducers that provide a switched ( shorted) output when a user defined Aac current level is exceeded. Commonly used for detecting cycle times, machine run times, machine state and equipment use studies. Adjustable and fixed threshold parts are available with current thresholds as low as 1.25 amps. Multiple wire loops can be used to increase sensitivity. Self-powered.
	AC Voltage	4-20mA or 0-5Vdc	DIN rail or surface mountable AC Voltage transducers with isolated analog 4-20mA or Vdc outputs corresponding to sensed Vac. Average RMS and true RMS parts available with ranges from 50Vac to 500 Vac full scale measurement range. Single phase and 3-phase parts are available
	AC Energy (kWh)	Switch (pulse)	Energy transducers with pulse outputs corresponding to measured power over time…. i.e. kWh energy. Various voltages, currents and wiring configurations are supported.
	AC Power - (kW)	4-20mA	Power transducers with analog outputs corresponding to instantaneous power ‘demand’ levels. Various voltages, currents levels and wiring configurations are supported. Note that most of our instruments can perform time integration of these power signals to result in a calculated Energy consumption value for logging, totalization and/or reporting.
	AC Energy and Power; Multi-Parameter Transducers	Modbus RTU (RS-485)	Multiple output parameter, electrical power transducers with Modbus outputs. Via the Modbus serial connection, one or more transducers can be networked to a single logger. 20+ electrical parameters can be accessed and logged and reported including phase voltages, phase currents, PF, frequency, kW, kWh, etc.
	Air Flow	4-20mA Pulse Modbus RTU (RS-485)	Compressed air and nitrogen air flow transducers (commonly used in compressed air audits)
