The direct reading scales eliminate troublesome conversions. The scales are brushed aluminum, coated with epoxy and the graduations are on both sides of the indicating tube. Special integral flow guides stabilize the float throughout the range to keep it from hunting or wandering in the bore. The float is highly visible against a white background.
The 4-digit LCD can display readings in common English and metric units so conversions are not necessary. The simplified four button operation reduces set up time and simplifies calibration with its digital push button zero and span. All models are factory calibrated to specific ranges.
Designed to measure and control positive, negative, or differential pressures consisting of non-combustible and non-corrosive gases. The gauge reading is independent of switch operation, and switching status is visible by LED indicators located on the front and rear of the gauge. Setpoints are adjusted with push buttons on the back of the unit.
Features a high ±0.25% or ±0.5% full-scale accuracy, and the four-digit digital display will reduce the potential for errors in readings. The gauges are battery-powered and have an auto-shutoff to conserve battery life, as well as a four-button keypad that allows easy access to features.
Movable dial with blue pressure markings and red temperature markings make the instrument easy to read. Pressure is indicated in both psi and kPa, while temperature is measured in both Fahrenheit and Celsius. Series TRI comes in three different connection options including lower mount, center back mount, and center back mount with extension shank.
Designed for pressure, vacuum, and differential pressures. The dual scaled adjustment knob in inches water column and pascals allows changes to the switching pressure to be made without a pressure gauge. The ADPS/EDPS is available with settings from 0.08 in w.c. (20 Pa) up to 20 in w.c. (5000 Pa).
Features field adjustable set point and gold inlay contacts. Air or other compatible fluids can be used on the "high side". The lightweight and compact size make the MDA ideal for any application with space constraints. Applications include industrial, HVAC/R, pump and motor control, medical, automotive, pools and spas.
The Series MDS Pressure Switch is designed with a double diaphragm to protect false actuation due to shock and vibration. This low cost pressure switch has a minimum 20 million cycle life expectancy, and an extremely fast response time, making this an ideal device for OEM orders.
