Our HVAC Humidity Transmitters are 4...20 mA current loop humidity transmitters. They are designed to provide precise signal accuracy with long-term stability in HVAC and Industrial Air Handler applications.

Our HVAC Switches include Differential Airflow switches, Low-limit Temperature switches, and AC Current switches. Our Differential Airflow switch is a general purpose airflow-proving switch that senses positive, negative, or differential air pressure. Our Low-limit Temperature switch provides a switched output based on the average temperature detected along a 6 m (20 ft) capillary sensor. Our AC Current switch is a solid-state switch that activates a contact closure whenever the monitored primary circuit current exceeds 1.5 A.

Our HVAC Pressure Transmitters measure positive, negative or differential pressure in the ranges of 1.00...12 in. wc (25.4...304.8 mm wc). The piezo resistive sensor monitors the pressure for air or other clean inert gas. Our Current-to-Pneumatic transducer converts a 4...20 mA input signal to a pneumatic output signal to position pneumatic damper and valve actuators in HVAC systems.

Bulletin 840E Solid-state Level Switches are microprocessor-based and designed to withstand harsh industrial conditions and wash-down applications such as liquid level monitoring in tanks, containers and pipelines. Available in both AC and DC versions, these switches are not affected by foam and are immune to vibration and build-up.
