Monitor System Pressures

These sensors are smaller than traditional mechanical pressure switches and have no moving parts to stick or break. Two series are offered. The PTD Series pressure and vacuum transmitters detect system pressure and convert it into an analog output signal for reliable pressure indication. Pressure transmitter output options include 4-20mA or 0-10V, and are available in sensing ranges up to 1,000psi. Vacuum-style transmitters offer 20-4mA or 10-0V outputs. All transmitters are priced at $125. The PSD Series electronic pressure switches feature a 316 stainless steel process connection and gas-tight measuring cell to reliably detect gas and liquid pressure. The switch withstands aggressive media and detects pressure ranges up to 5800psi (400bar). Mechanical adjustment dials rotate quickly to establish the set point and reset point. All switch models are priced at $89.AutomationDirectwww.automationdirect.com800.633.0405
