On/Off Level Controllers (11 suppliers)
On/Off level controller is the simplest form of temperature control device. The output from the device is either on or off, with no middle state. This will switch the output only when the temperature crosses the set point. This prevents the output from chattering or making fast, continual switches if the cycling above and below the set point occurs very rapidly. They are commonly used in simple applications such as thermostats in heating systems and domestic refrigerators. They are modified to include a dead band for the error signal to reduce the sensitivity to measurement noise. This is sometime referred to as two-position or bangs control. One special type of on-off control used for alarm is a limit controller. This uses a latching relay, which must be manually reset, and is used to shut down a process when a certain temperature is reached. They are inexpensive and easy to implement. The disadvantage of these controllers is the cycling of the controlled variable, which is unacceptable in a quality control problem and usually leads to excessive wear and tear on the final control element.

Once Through Oil Sealed System (3 suppliers)
Once through oil sealed system is a vacuum pump especially designed for corrosive applications. In every cycle, fresh oil is fed into the bearings and as a sealant, this greatly reduces internal parts wear and pump failure. Limiting the amount of lubricant used to protect bushing and pump internal allows this system to run at operating temperature, which keeps the process vapors in the gaseous state thus eliminating condensation within the pump body.

Once-Thru-Oil Rotary Vane Vacuum Pumps (2 suppliers)
OTO Rotary Vane Vacuum Pumps are designed to handle solvent and corrosive vapors found in chemical and pharmaceutical vacuum applications such as distillation and vacuum drying. Although the pumps do use oil on a once thru basis, which must be disposed of, oil usage is very low. The corrosive vapor handling capability is one of its primary features, as this is accomplished with standard pump materials but the accessories for pump protection must be in corrosion resistant materials.
