We offer a complete product range of Split-Core Current Switch, Ultra High Purity Flow Through Pressure Sensor, Sure-Set Split-Core Current Switch, Mini Current Switch and Solid-Core Current Switch
Setra’s Model CSC split-core current switches provide a cost effective solution for real-time monitoring of motor status in common HVAC applications. The CSC is available with fixed or adjustable trip set-point values alerting the user to over or under current conditions in the application, with trip points as low as 0.15 A up to 135 A. Setra’s design utilizes magnetic induction current sensing technology allowing the CSC switches to accurately operate over a wide range of environmental conditions, without the need for an additional power supply. The current switch is available with a snap-on power relay designed to start or stop AC motors during tripped setpoint conditions, minimizing service time in the field.
Setra's Model 224 224 ultra-high purity pressure transducer is designed for the most demanding specialty gas monitoring and control applications, where construction integrity, purity and performance cannot be sacrificed. The 224 has a small, streamlined sensor chamber for easy purgeability. The sensor is designed to provide superior mechanical and thermal stability, especially in transient temperature conditions resulting from flowing gases. Isolation of the sensing element from the pressure fitting virtually eliminates any torque effects. The superior mechanical and thermal stability is achieved through Setra's patented variable capacitance sensor. Its fundamentally simple design features VAR 316L SS wetted parts, passivated to 5 Ra (7 Ra. max.) fi nish for system continuity, and an insulated electrode plate fastened to the center of the sensor diaphragm, which forms a variable capacitor. As pressure increases or decreases, the capacitance changes. This change in capacitance is detected and converted to a linear analog signal by Setra’s unique electronic circuit.
Setra’s Sure-Set™ Model SSC current switch is the safest current switch for under current sensing on constant speed drive applications. The split-core current switch provides a unique approach to calibration and installing current sensors, utilizing the horsepower of the motor. This eliminates exposure to arc flash vs. traditional adjustable set point switches on the market. The multi-range dial maximizes flexibility and reduces overall installation time, allowing installation to be done on a cold circuit without the need for an arc flash suit and protective equipment. The SSC’s recessed set point dial reduces the chance of inadvertent adjustments, while the detents provide tactical feedback that the desired horsepower rating has been selected. Avoid Arc Flash Traditional adjustable current switches require the installer to make set point adjustments to the unit on a live circuit during installation increasing the safety risk to the installer. Each SureSet™ model offers 9 pre-configured set points so the installer can pre-configure the switch, based on the rating of the motor, prior to powering the circuit, eliminating the risk of arc-flash hazard.
Setra’s Model CCM is the industry’s smallest split-core current switch offering a cost effective solution for monitoring light to medium current loads in common HVAC applications. It is designed to detect increases or decreases in operating current based on belt loss, slippage or mechanical failure within a process. The CCM incorporates an integrated DINrail and surface mounting flange for easy installation in any application, at no additional cost. The Mini Current Switch is easily clamped onto new or existing power cables or wires, making it ideal for new construction and retrofit projects.
Setra’s Model CSS solid-core current switches provide a cost effective solution for real-time monitoring of motor status in common HVAC applications. The CSS is available with fixed or adjustable trip set-point values alerting the user to over or under current situations in the application, with trip points as low as 0.25 A up to 135 A. The Model CSS’s design utilizes magnetic induction current sensing technology allowing the CSS switches to accurately operate over a wide range of environmental conditions, without the need for an additional power supply. The current switch is available with a snap-on power relay designed to start or stop AC motors during tripped set-point conditions, minimizing service time in the field.
