Dakota Instruments, Inc. products

Pulse width modulated Driver Modules regulate the power supplied to the Proportionating Electromagnetic Valves based on a reference signal. Set-point signals, 0-5 Vdc or 4-20 mA, input are employed to control the output pulse width modulated voltage at a fixed frequency (≈30KHz) and amplitude. Incoming power to the valve coil is applied and discontinued for predetermined periods of time by a low loss solid state switching element. The wide range of power input features conveniently accommodates 12 to 32 Vdc sources. The Auto-Select feature of the Driver Module recognizes the type of reference signal received and defaults to 0 - 5 Vdc if both signals are provided.

Small in size but big in value, Digi-Sense`s affordable, compact vane anemometer verifies proper airflow for component or space cooling. Seven user-selectable units deliver accurate airflow measurements. Ergonomically placed push buttons and a small comfort grip allow easy selection of either maximum or average air velocity readings.

Digi-Sense`s CFM/CMM Thermoanemometer provides precision air velocity and airflow measurements with seven user-selectable units and is ideal for meeting your environmental and cooling requirements. The user-friendly dual display provides simultaneous readings of air velocity or airflow and air temperature. The large dual-function 4-digit LCD with backlight allows easy reading in dimly lit conditions. Auto Power Off extends battery life.

Compact and self-contained, Dakota`s Mass Flow controllers are designed to indicate and control flow rates of gases. GC mass flow controllers combine the characteristics and accuracy of conventional mass flow devices at low costs previously unattainable. Available in flow ranges from 10 mL/min to 1000L/min relative to Nitrogen, each model is calibrated on-site with numerous gas selections, including gas mixtures offered. For gases and gas mixtures not shown consult with Dakota. These high precision controllers have +/-1% full scale accuracy for models up to 100 Liters per minute.
