Clark Solutions offers a wide range of pressure gage, differential pressure gage, pressure transmitter, pressure switch, explosion-proof differential pressure switch, and vacuum switch products. Selected models from each of these product groups includes:

Pressure Transmitters
The 100 Series current output pressure transmitters were designed to provide a previously unequalled level of performance, utilizing Piezo Resistive or Thin film sensor technology dependent on pressure range.

The Series 110 Sanitary Pressure Transmitter is designed for heavy-duty sanitary applications where high accuracy and durability are required.

The Model 511 compact OEM pressure transmitters meet the highest specification for mechanical stress, EMC compatibility, and operational reliability and are particularly suitable for demanding industrial applications.

Pressure Gages
The Model 400 Pressure Gage (dry) and Model 500 Pressure Gage (liquid filled) series all stainless steel gages are the ultimate in corrosion resistant, heavy duty, vacuum and pressure gauges.

Differential Pressure Gage
Select the Magnehelic¨ differential pressure gage for high accuracy - guaranteed within 2% of full scale and for the wide choice of ranges available to suit your needs precisely.

Pressure Switch
The 604 differential pressure switch is typically used for system interlock and alarm in ventilation ducts for monitoring of filter and fan pressures.

Differential Pressure Switch
The 1800 Series is one of our most popular differential pressure switches. Combines small size and low price with 2% repeatability for enough accuracy for all but the most demanding applications.

Explosion-Proof Differential Pressure Switch
Model 1950 Explosion-Proof Differential Pressure Switch combines the best features of the popular series 1900 with an integral explosion-proof and weatherproof housing, making it an exceptional value for either application.

Vacuum Switch
Model VM is a simple, reliable low cost vacuum switch that uses a spring-loaded diaphragm as the sensing element.
