Siemens Building Technology 357-0003 Thermostat
The Siemens 357-0003 Powers Limitem is a heavy-duty pneumatic thermostat designed for precise temperature regulation in air handling systems and unit ventilators. As a direct acting remote bulb thermostat, this unit provides a proportional pneumatic signal based on liquid-filled sensing technology. This model features a 20°F to 100°F operating range, making it an ideal choice for low-limit control or primary discharge air sensing where a 3/8-inch x 4-inch remote bulb is required for accurate placement away from the mounting body.
Built for the demands of commercial HVACR infrastructure, the Siemens TH 357 Limitem utilizes a two-valve design that significantly reduces air consumption while maintaining a rapid response to temperature change. The 8-foot capillary provides the necessary reach for duct or pipeline installations, ensuring the liquid-filled sensing element can be positioned in the optimal airflow or fluid stream. With an adjustable sensitivity range of 1/3 to 3-1/2 psi/°F, technicians can fine-tune the control loop to prevent hunting and ensure steady-state performance of connected pneumatic actuators and valves.
- Precise Control: Features direct acting logic where output pressure increases as the sensed temperature rises.
- Versatile Mounting: Includes a 1/8-inch NPT air connection and universal mounting bracket for standard field installation.
- High Sensitivity: Field-adjustable sensitivity ensures compatibility with various pneumatic control sequences and damper requirements.
- Liquid-Filled Accuracy: The 357-0003 utilizes a thermal-expansion sensing bulb for reliable data regardless of ambient case temperature.
Common Questions
What is the maximum supply air pressure for this unit?
The 357-0003 is designed to operate with a clean, dry, oil-free supply air pressure of up to 30 psi, though standard pneumatic systems typically run at 18 to 25 psi.
Can this thermostat be used for reverse acting applications?
No, the Siemens TH 357 series is specifically available as a direct acting thermostat. For reverse acting requirements, reference the TH 356 rigid bulb series.
Is the sensing bulb compatible with immersion wells?
Yes, for pipeline applications, the 3/8-inch remote bulb can be installed in a standard copper well to monitor water or liquid temperatures.
