Taco adds a new differential pressure sensor to its extensive line of hydronic system components. The sensor relays system performance information to a variable frequency drive or to a building management system. The Taco DPS629 monitors differential pressures of air and compatible gases and liquids. The design uses dual sensors that convert pressure changes into a standard 4-20 mA output signal for two-wire circuits. Its small size and few moving parts make for exceptional response time and reliability. Terminal block, zero and span adjustments are easily accessed under the top cover. Designed to meet NEMA 4x (IP66) construction, the unit is applicable for flow elements, heat exchangers, filters, pumps and coils.
