series byds bypass damper switch
controls zone static by modulating motorized damper
the series byds bypass damper switch is designed to control motorized bypass dampers. As individual zone dampers open and close, the system static pressure will rise and fall. In order to maintain proper airflow and static pressure through the hvac system, a bypass system incorporating a floating type motorized damper and a static pressure control should be incorporated. A typical on/off pressure switch cannot operate in this application due to the high cycle rate that would result, eventually causing contact burnout. The byds static pressure control is equipped with a solid-state switching and timing circuit to enhance operation and improve long-term reliability in this demanding application.
control operation
the byds bypass damper switch is designed for use with a three wire floating point damper actuator used to control the static pressure on zone control systems requiring motorized bypass dampers. A bypass damper, bypasses air from the discharge air side of the hvac unit back in the return air side. The air flow is modulated in order to maintain a constant static pressure in the system as individual zone dampers open and close. The static pressure control is equipped with solid-state switching which dramatically increases the life of the control. On an increase in static pressure the byds will send 24 volts out and start the actuator to drive open. When the static pressure reaches set-point the actuator will stop. After a ten second delay the actuator will start to drive the damper closed if there has not been an increase in static pressure. A green led indicates when the damper is in the open position or being driven open. A 24 vac transformer is required to power the byds control and damper actuator. The unit includes tubing and two static pressure probes.
additional ranges can be found on the series adps/edps web page.

Single Stage Top Mount Displacer Type Level Control
Series 190 Single Stage Top Mount Displacer Type Level Control
Fixed or Adjustable Deadband, For Pumps or Alarms
The most versatile liquid level controls in our line, displacer controls can be used to trigger alarms, provide shutdown or operate pumps.
Operation: Mercoid Displacer Controls use displacers that do not float on the surface of liquids, but are suspended on a coil spring. They work on the principle that submerged solids weigh less in liquids, and as the liquid level rises and their weight decreases, the tension on the spring by which they are suspended is decreased. This allows the spring to move the cable and armature upward, actuating the hermetically sealed switches. Because they work on a different principle than float type liquid level controls, displacers are not affected by turbulence, or pressure, and are excellent for applications with viscous or dirty liquids.
Dimensions are based on 316SS displacers with 4" minimum flange type control. All dimensions are approximate and will vary depending on specific gravity, temperature, displacer material and size. Critical dimensions must be verified with the factory before placing order.
Standard Construction: 316SS displacers, 10 foot 316SS cable and stops, 49 125# CI flange: for operation in specific gravities as low as 0.5 and a maximum temperature of 200F (93C). For special conditions, other choices include: 316SS displacers: longer cable: monel or hastelloy cable and stops: other flange sizes, materials or pressure ratings, or 3/4" NPT top connection in lieu of flange.

piston vibrator
series apv piston vibrator
air cushioned or piston vibrators
series apv-c piston vibrators are air cushioned to provide low noise. This makes it suitable for quiet area applications. It is a good solution to prevent clogs on tank walls and material delivery problems. It can also be applied on vibrating separators and conveyors.
series apv-i impact version piston vibrators can help to get rid of dust or material accumulated inside of pipes or tanks. It allows direct impact on the tank with low specific gravity and high moisture materials inside. It also helps prevent material build-up, pipe clogs, and rust.
how it operates
there are air-breathing tubes located in both ends of the cylinder. Compressed air pushes the piston from one side to the other. Vibration power arises when the piston moves back and forth in the body. In apv-c air cushion at both ends produced by the to-and-fro motion will keep the piston from striking the body. Therefore, the piston will not produce much noise. In apv-i, air cushion at the top end is produced by the to-and-fro compression. This will keep the piston from striking onto the body top. The piston will strike directly on the bottom side of the body to produce a strong impact.

Used in Dusty Environments
A wide variety of fittings for use with most Dwyer products. Special line filters for the Magnehelic Gage and Capsuhelic Gage allow use with dusty environments. Particulate filters are used for Dwyer Flowmeters to keep the air clean.
The Muffler Accessory can be easily field installed to any diaphragm valve with an exhaust. Pneumatic exhaust ports are on the diaphragm valves that have dual diaphragms and the units with the integral mounted solenoid. The muffler decreases the amount of noise when the air is exhausted from the valve. Valves with dual diaphragms and an integral solenoid have two exhaust ports and will require one A-237 and one A-238.

Digital Touch Screen Programmable Thermostat with Heat Pump Control
Model TLVT1 Digital Touch Screen Programmable Thermostat with Heat Pump Control
5 Control Modes, Large LCD Display
The MODEL TLVT1 Digital Touch Screen Programmable Thermostat with Heat Pump simplifies controlling indoor temperatures in commercial and residential buildings. A large easy to read LCD display shows the current temperature, set point, as well as time and day of the week. By touching the icons on the display, building occupants can temporarily change the set point, edit the weekly program, or select the control mode. For larger offices or homes, a single thermostat can control up to two heating and two cooling units. For Heat pump applications, the thermostat can control a two stage compressor. To make programming the time easier, there is a daylight savings time function that will automatically change the time based on the US time change dates. To prevent tampering, the Model TLVT1 has a security code feature that can lock out the programming. For additional energy savings, the filter, UV and energy usage timers tracks the number of hours the fan, heater/cooler, and thermostat is powered on. Additional energy savings can be achieved by programming the thermostat for up to 4 temperature events for each day of the week.
